All living things require a constant supply of energy in order to survive. Thereby, in anoxygenic photosynthesis, oxygen gas is not liberated as a by-product. Photosynthesis occurs in the leaves of plants with li… The chloroplast uses the energy harnessed from these photons and their interaction with the cytochromes and other proteins to drive the formation of glucose. Cellular respiration takes place in all living organisms in mitochondria, whereas photosynthesis occurs only in plants containing chlorophyll. Plants perform photosynthesis to create their own food source and use cellular respiration to unlock the energy from that food. In the cellular respiration oxidative phosphorylation occurs. The energy is in the form of glucose or chemical energy, which is used during the dark reaction. This process occurs in the chloroplasts, using chlorophyll. This organic compounds can be used by cells as food. This process of electron transportation is called photophosphorylation. Plants, algae, and cyanobacteria carry out oxygenic photosynthesis while purple sulfur bacteria and green sulfur bacteria carry out anoxygenic photosynthesis. Cellular Respiration: Glycolysis, Citric acid cycle and electron transport chain are the three steps in cellular respiration. Chlorophyll is green because the light required for photosynthesis is red and blue light, leaving green light to be reflected back to our eyes. The first stage of cellular respiration is the glycolysis. Photosynthesis: Photosynthesis is an anabolic process, which synthesizes complex organic compounds. During anaerobic respiration, the final electron acceptor is either inorganic sulfates or nitrates.
