Photosynthesis and aerobic respiration are both cellular processes that happen in order to create energy for the organism they’re taking place in. All forms of life need energy in order to work properly, but not all forms of life get this energy the same way. For more complex organisms, such as animals and fungi, this energy is obtained in the food they consume.
Aerobic cellular respiration
Reactants: C6H12O6+O2
Products: CO2+H2O+ATP
Aerobic respiration takes place when sugar is oxidized in the presence of oxygen in a series of reactions that make the sugar molecules smaller and smaller. It should be noted, that these reactions create energy by breaking the bonds of the molecules involved. The first stage involves a biochemical pathway named glycolysis, a series of reactions that take place in the cytoplasm of the cell that initiates the breakdown of a 6 carbon molecule, glucose, obtained from food. These glucose molecules break down in the cell’s cytoplasm- and react with oxygen gas so that energy can be released. Two ATP molecules start the process, by adding two phosphates to the starting 6 carbon molecule, which is then divided in half, making up two 3-carbon sugar phosphates. The reaction finalizes with the conversion of the two 3-carbon

This process takes place within the stroma that surrounds the thylakoid membrane. Carbon fixation is very important for the Calvin cycle; with the aid of an enzyme called RuBisCo, it reduces the carbon dioxide molecule to a 5-carbon sugar, ribulose 1,5-biphosphate (RuBP). It results in a very large, unstable molecule that ends up splitting into two 3-carbon molecules. The ATP and hydrogen from NADPH bind to these 3-carbon molecules and are then combined to form glucose or to make up other molecules. Most of these 3-carbon molecules are used to regenerate the starting 5-carbon
In the light independent stage of photosynthesis ATP is again used to break down a molecule. In the Calvin cycle after glycerate 3-phosphate is reduced, then ATP breaks down and loses a phosphate group (becoming ADP). The phosphate group is then gained by the glycerate 3-phosphate molecule and it becomes triose phosphate. ATP is then used furthermore in product synthesis (anabolism) this is where energy is required to convert the triose phosphate into more complex molecules such as amino acids or lipids.
Cellular respiration is a chemical reaction used to create energy for all cells. The chemical formula for cellular respiration is glucose(sugar)+Oxygen=Carbon Dioxide+Water+ATP(energy) or C6H12+6O2=6CO2+6H2O+ energy. So what it is is sugar and
Cellular respiration and photosynthesis are important in the cycle of energy to withstand life as we define it. Cellular respiration and photosynthesis have several stages in where the making of energy occurs, and have diverse relationships with organelles within the eukaryotic cell. These processes are central in how life has evolved.
Do you know how you are able to run long distances or lift heavy things? One of the reasons is cellular respiration. Cellular respiration is how your body breaks down the food you’ve eaten into adenosine triphosphate also known as ATP. ATP is the bodies energy its in every cell in the human body. We don’t always need cellular respiration so it is sometimes anaerobic. For example, when we are sleeping or just watching television. When you are doing activities that are intense like lifting weights or running, your cellular respiration becomes aerobic which means you are also using more ATP. Cellular respiration is important in modern science because if we did not know about it, we wouldn’t know how we are able to make ATP when we are doing simple task like that are aerobic or anaerobic.
Overview of Cellular Respiration and Photosynthesis Written by Cheril Tague South University Online Cellular Respiration and Photosynthesis are both cellular processes in which organisms use energy. However, photosynthesis converts the light obtained from the sun and turns it into a chemical energy of sugar and oxygen. Cellular respiration is a biochemical process in which the energy is obtained from chemical bonds from food. They both seem the same since they are essential to life, but they are very different processes and not all living things use both to survive ("Difference Between Photosynthesis and Cellular Respiration", 2017). In this paper I will go over the different processes for photosynthesis and the processes for cellular respiration and how they are like each other and how they are essential to our everyday life.
Photosynthesis and cellular respiration help sustain life on planet earth as both are metabolic processes in their own way. Photosynthesis is the process by which plants and other organisms use energy from the sun to form glucose from water and carbon dioxide. From there, glucose is then converted to ATP by way of cellular respiration. To convert nutrients that are biochemical energy into ATP, a process such as cellular respiration that has reactions needs to take shape in the cell of an organism, releasing waste products at the same time. For the continuous energy cycle that tolerates life on Earth as we know it Photosynthesis and Cellular respiration very essential. They have a few stages where energy and various connections occur within the eukaryotic cell. Cellular respiration takes place in the lysosome, an organelle that is found in the cytoplasm of eukaryotic cells. It uses enzymes to break down biomolecules including proteins, nucleic acids, carbohydrates, and lipids. Photosynthesis involves the chloroplasts, which contain pigments that absorb the sunlight and then transfigure them to sugars the plant can use. Those specific processes are crucial in how far and diversified evolution has
Aerobic requires oxygen and takes place inside the mitochondria of iving cells. The energy is stored as adenosine triphosphate (ATP) Aerobic respiration produces 2890KJ/Mole or 38ATP. This is much more than anaerobic. The
“Photosynthesis (literally, “synthesis from light”) is a metabolic process by which the energy of sunlight is captured and used to convert carbon dioxide (CO2) and water (H2O) into carbohydrates (which is represented as a six-carbon sugar, C6H12O6) and oxygen gas (O2)” (BioPortal, n.d., p. 190).
This equation also shows fermentation process, which proves an anaerobic respiration, which means that oxygen is absent from the process. Anaerobic respiration takes place in organisms and releases a small amount of energy very quickly. In most organisms, it consists of a chain of chemical reactions called glycolysis, which break down glucose into pyrutic acid.
TutorVista.com (2015), states that; “photosynthesis and cellular respiration are metabolic reactions that complete each other in the environment. They are the same reactions but occur in reverse. In photosynthesis, carbon dioxide and water yield glucose and oxygen respiration, process glucose and oxygen yield carbon dioxide and water, catabolic pathway process which requires or contains molecular oxygen for the production of adenosine triphosphate. This three step aerobic respiration cycle occurs in the cytoplasm and in the organelles called mitochondria. Within this process, cells break down oxygen and glucose in its storable form called adenosine triphosphate or ATP. This cellular respiration or sometimes called an exothermic reaction is similar to a combustion type reaction whereby the cell releases energy in the form heat but at a much slower rate within a living cell. According to our text, Campbell Essential Biology with Physiology, (2010, pg. 94), cellular respiration is stated as “The aerobic harvesting of energy from food molecules; the energy-releasing chemical breakdown of food molecules, such as glucose, and the storage of potential energy in a form that cells can use to perform work; involves glycolysis, the citric acid cycle, the electron transport chain, and chemiosmosis”. It is also my understanding that it is possible for cellular respiration to take place without oxygen, which is called anaerobic respiration. In the anaerobic respiration process the glycosis step or sometimes referred to as the metabolic pathway process deferrers because the anaerobic condition produces
Photosynthesis is a process in plants that converts light energy into chemical energy, which is stored in bonds of sugar. The process occurs in the chloroplasts, using chlorophyll. Photosynthesis takes place in green leaves. Glucose is made from the raw materials, carbon dioxide, water, light energy and oxygen is given off as a waste product. In these light-dependent reactions, energy is used to split electrons from suitable substances such as water, producing oxygen. In plants, sugars are produced by a later sequence of light-independent reactions called th...
Photosynthesis is a process in which plants and other organisms convert the light energy from the sun or any other source into chemical energy that can be released to fuel an organism’s activities. During this reaction, carbon dioxide and water are converted into glucose and oxygen. This process takes place in leaf cells which contain chloroplasts and the reaction requires light energy from the sun, which is absorbed by a green substance called chlorophyll. The plants absorb the water through their roots from the earth and carbon dioxide through their leaves.
Photosynthesis is a key contributor to all living things; photosynthesis provides the oxygen, food, and nutrients that help all living things stay healthy and alive. Photosynthesis converts solar energy into the chemical energy of a carbohydrate. Photosynthetic organisms, including land plants, algae, and cyanobacteria, which are called autotroph...
When humans consume plants, the carbohydrates, lipids, and proteins are broken down through two forms of cellular respiration. The two processes of cellular respiration displayed in humans are anaerobic and aerobic. The deciding process used depends on the presence of oxygen. Cellular respiration converts the material into a useable energy called ATP. ATP is the energy form that cells can use to perform their various functions, and it can also be stored for later use.
Photosynthesis is the process in which living cells from plants and other organisms use sunlight to produce nutrients from carbon dioxide and water, the image below “Diagram of photosynthesis 1,” helps show this process. Photosynthesise generally creates oxygen as a by-product through the use of the green pigment, chlorophyll, found in the plant that helps this reaction occur. “Photosynthesis provides us with most of the oxygen we need in order to breathe. We, in turn, exhale the carbon dioxide needed by plants,” (factmonster,2017). This is able to show us why photosynthesis is so greatly needed to occur through plants in order to give one another essentials needed for continuity of life. “Plants perform photosynthesis because it generates the food and energy they need for growth and cellular respiration,” (photosynthesieeducation, 2016).
