Recommended: The historical perspective of photosynthesis

C3 photosynthesis is the ancestral form of photosynthesis and is present in the majority of plant species (Sage, Sage & Kocacinar 2012). In this process CO2 enters the mesophyll cell (mc) via openings in the epidermis called stomata and diffuses into the into the chloroplast where it enters the Calvin cycle (Raven, Evert & Eichhorn 2013). The Calvin cycle is made up of three stages: 1. Carboxylation of Ribulose-1,5-bisphosphate (RuBP). In which a molecule of CO2 is covalently bonded to a molecule of RuBP forming the first stable intermediate 3-Phosphoglycerate. It is from this 3 carbon product that the name C3 photosynthesis comes from. This reaction catalysed by the enzyme Ribulose-1,5-bisphosphate carboxylase-oxygenase (Rubisco) 2. Reduction of 3-phosphoglycerate to the carbohydrate glyceraldehyde-3-phosphate, utilizing the ATP and NADPH formed in the light harvesting reactions. 3. Regeneration of the initial substrate RuBP (Taiz & Zeiger 2006). These stages encompass thirteen different reactions the net result of which is:
3CO2+5H2O+6NADPH+9ATP→glyceraldehyde-3-phosphate+6NAD...

    Before learning about photosynthesis, I thought this was just a way for plants to grow, not knowing the full detail that goes on inside the plant for it to grow. So, after learning about what photosynthesis is and how it truly works, it is something that is remarkable and how plants are really the only living thing that uses this process. Photosynthesis is the process of taking in carbon dioxide (CO2), which is a gas that is exhaled from animals and goes into the air and is absorbed into a plant, water (H2O) which is absorbed through the roots of a plant or known as capillary action, sunlight is absorbed through chloroplasts which contain chlorophyll or better known as the leaves of the plant. With the photosynthesis process, the plant can create a by-product known as oxygen gas which is released through the little pores into the atmosphere (Simon, Dickey, Hogan & Reece, n.d.).

    With the sunlight, four pigments in his chloroplasts absorb the sunlight. These four pigments are carotenes, xanthophylls I and II, and chlorophyll b. These pigments will then convert the sunlight to chemical energy, which then transfers to chlorophyll a. Chlorophyll a then splits six water molecules (6 H2O) into twelve hydrogen atoms (12 H) and three oxygen molecules (3 O2). The coenzyme NADP then holds the product of twelve hydrogen atoms (12 H) as 6 NADPH2 to carry to the next process. The three oxygen molecules (3 O2) are then released into the air as a byproduct.

    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.

  • What Is Autotrophs?

    1642 Words  | 4 Pages

    The two 3-carbon pyruvate molecules that were created from glycolysis are oxidized. One of the carbon bonds on the 3-carbon pyruvate molecule combines with oxygen to become carbon dioxide. The carbon dioxide leaves the 3-carbon pyruvate chain. The remaining 2-carbon molecules that are left over become acetyl coenzyme A. Simultaneously, NAD+ combines with hydrogen to become NADH. With the help of enzymes, phosphate joins with ADP to make and ATP molecule for each pyruvate. Enzymes also combine acetyl coenzyme A with a 4-carbon molecule called oxaloacetic acid to create a 6-carbon molecule called citric acid. The cycle continuously repeats, creating the byproduct of carbon dioxide. This carbon dioxide is exhaled by the organism into the atmosphere and is the necessary component needed to begin photosynthesis in autotrophs. When carbon is chemically removed from the citric acid, some energy is generated in the form of NAD+ and FAD. NAD+ and FAD combine with hydrogen and electrons from each pyruvate transforming them into NADH and FADH2. Each 3-carbon pyruvate molecule yields three NADH and one FADH2 per cycle. Within one cycle each glucose molecule can produce a total of six NADH and two

  • Rubisco Case Study

    Rubisco appears in the stroma of chloroplast in its inactivated form. According to Salvucci and Crafts‐Brandner (2004), Rubisco is activated and regulated by Rubisco activase (RCA). Rubisco activase is classified as AAA+( ATPase associated with variety of cellular activity) (Neuwald et al., 1999), and is mostly found on the chloroplast stroma. This activase enzyme activates Rubisco which later catalyzes the carboxylation of RuBP; furthermore, this carbon dioxide fixation is the first photosynthetic CO2 assimilation (Keys, 1986). In the presence of ATP, RCA activates Rubisco by removing phosphate sugar on its active site which acts as Rubisco’s inhibitor (Tabita et al., 2008). The activation of Rubisco is endergonic because it requires energy in the form of

    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.

    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.

Cellular respiration and Photosynthesis form a cycle of that energy and matter to support the daily functions that allow organisms to live. Photosynthesis is often seen to be one of the most important life processes on Earth. Photosynthesis is a process by which plants use the energy of sunlight to convert carbon dioxide and water into glucose so other organisms can use it as food and energy. It changes light energy into chemical energy and releases oxygen. This way organisms can stay alive and have the energy to function. Chlorophyll is an organelle generally found in plants, it generates oxygen as a result too. As you can see without

    The Importance of Photosynthesis and What it Does for Life According to scientists, life is “the condition that distinguishes animals and plants from inorganic matter, including the capacity for growth, reproduction, functional activity, and continual change preceding death, also the way of life of a human being or animal. ”("Life,”) In order for one to have life, one must have the nine characteristics to be considered a living thing. These nine characteristics are: all living things are made up of cells, living things are able to reproduce, living things use energy, maintain homeostasis, respond and adapt to the environment, grow and develop, have a life span, evolve over time, and are interdependent. All of the nine characteristics have one thing in common, something that is needed for all living things to work, even if they do not know it.
