AP Bio Reflection
My game was focused around mechanism of energy transfer which includes photosynthesis reactions and respiration reactions. Photosynthesis takes place in two stages, the light-dependent reactions and light-independent reactions. Light-dependent reactions are when sunlight is absorbed by the chlorophyll and used for energy which is then converted into stored chemical energy. This chemical energy is in the form of NADPH and ATP. These reactions take place in the thylakoid, inside the chloroplast. Light-independent reactions or the Calvin Cycle use energized electrons from light-dependent reactions as energy. This energy is used to form carbohydrates from carbon dioxide molecules. Light-independent reactions require the products of light-dependent reactions in order to function. Energy carrier molecules, ATP and NADPH are what construct the new carbohydrates molecules. Cellular respiration is the breaking down of sugar in the presence of oxygen. It occurs partially in the cytoplasm as well as the mitochondria. It can be broken up into four stages which include glycolysis, transition reaction, Krebs Cycle, and Electron Transport Chain (ETC). Glycolysis is where one glucose is broken down into two molecules of pyruvic acid. Transition Reaction then shuttles the pyruvic acid to the mitochondria, where it …show more content…

Photosynthesis creates energy that is released during cell activity. Interactions between all species is needed for life to stay in balance. Photosynthesis is largely responsible for producing the oxygen on Earth and its atmosphere. It supplies organic compounds used to build materials used by us such as wood and cotton. Photosynthesis is the process in which new energy becomes available. It is also the source of energy stored in fossil fuels. Without photosynthesis and respiration, life on earth couldn’t exist. Ecosystems and cascades wouldn’t be able to

  • Cellular Respiration And Photosynthesis Essay

    1028 Words  | 3 Pages

    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 Essay

    1372 Words  | 3 Pages

    The process of photosynthesis is present in both prokaryotic and eukaryotic cells and is the process in which cells transform energy in the form of light from the sun into chemical energy in the form of organic compounds and gaseous oxygen (See Equation Below). In photosynthesis, water is oxidized to gaseous oxygen and carbon dioxide is reduced to glucose. Furthermore, photosynthesis is an anabolic process, or in other words is a metabolism that is associated with the construction of large molecules such as glucose. The process of photosynthesis occurs in two steps: light reactions and the Calvin cycle. The light reactions of photosynthesis take place in the thylakoid membrane and use the energy from the sun to produce ATP and NADPH2. The Calvin cycle takes place in the stroma of the chloroplast and consumes ATP and NADPH2 to reduce carbon dioxide to a sugar.

    Photosynthetic pigments are essential for life because they allow photosynthesis to occur by capturing sunlight which is then used alongside carbon dioxide and water to form organic compounds such as glucose and oxygen. The pigments allow the conversion of light energy to chemical energy which other organisms can benefit from. Oxygen is utilised by other organisms in aerobic respiration. The different pigments present in the chloroplasts allow a wide variety of wavelengths of light to be absorbed for efficient photosynthesis and provide colours to the plant to attract pollinators.

    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 a 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.

    Synthetic biology, also known as synbio, is a new form of research that began in the year 2000. The Action Group on Erosion, Technology and Concentration (ETC Group) says that synthetic biology is bringing together “engineering and the life sciences in order to design and construct new biological parts, devices and systems that do not currently exist in the natural world’ (Synthetic Biology). Synthetic biology is aiming to create safer medicines, clean energy, and help the environment through synthetically engineered medicines, biofuels, and food. Because synthetic biology has only existed for fourteen years, there is controversy involving its engineering ethics. In this literature review, I am going to summarize and correlate the International Association for Synthetic Biology (IASB) Code of Conduct for Gene Synthesis, the impact of synthetic biology on people and the environment, and the philosophical debates.

    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.
