Processes of Photosynthesis and Cellular Respiration
Cellular respiration is the process of producing cellular energy. There are four steps in order to achieve the entire cellular respiration;Glycolysis, Pyruvate Oxidation, Citric Acid Cycle and the Electric transport chain. In Glycolysis, glucose undergoes a chemical transition in the cytosol and anaerobic respiration produces lactic acid. Before this however, oxygen must be present so the lungs have to take in oxygen and give out carbon dioxide to start glycolysis. Also, the small intestine takes glucose and other nutrients through digestive processes.Next, in Pyruvate oxidation, the pyruvate goes from the glycolysis to the mitochondrial matrix through the bloodstream. Here, carbon dioxide is released and NADH is generated. The mitochondrial matrix is where the processes take place. In the Citric Acid Cycle or Krebs Cycle, the acetyl CoA combines with a 4 carbon molecule. Lastly, in the Electric transport chain, the NADH is turned into oxygen molecules and give up the energy. The final result is the oxygen molecule. The chemical process is C6H12O6 + 6O2 → 6CO2 + 6H2O + energy.
Photosynthesis is the process of making food (glucose) for plants. It needs water (which is absorbed by the roots), which is taken up by capillary action through the stem and to the leaves. Sunlight (which is taken in by the chloroplasts, to convert into usable energy to carry out the process of photosynthesis), and carbon dioxide (taken in by the stomata in the leaves). This water, carbon dioxide, and sunlight then becomes oxygen and glucose, which is used by the plant to make energy. The chemical equation is 6CO2 + 6H2O + energy = C6H12O6 + 6O2. The first stage in photosynthesis is when energy is absorbed from the sun. The second stage is when light energy is converted into chemical energy, which is stored in ATP. Stage three in Energy in ATP powers formation of organic compounds using CO2.
