Photosynthesis and aer. respiration can be the same in many ways. For instance, both of them contain cycles. In photosynthesis, there is the Calvin cycle, and photosystem I, just producing ATP. In aer. respiration, there is the Kreb cycle. The equations for both of these processes are also similar, C6H12O6 + 602 --> 6CO2 + 6H2O + energy (aerobic respiration.) …show more content…
respiration is also very different. Photosynthesis takes place in the chloroplast of plants in the thylakoids and aer. respiration occurs in the mitochondrion of cells. Both processes have different purposes starting off with saying that photosythesis's goal is to make carbohydrates, lipids, or proteins and the goal of respiration is to make ATP, water and have oxygen as the final hydrogen acceptor. There is no FADH+ in photosynthesis, a lower electron acceptor, and no photophosphorylation in aer. res. The cycles of the 2 are similar all in that there are different molecules put in and different enzymes used. In the Kreb cycle, a pyruvic acid goes from the cytosol after being formed from a split glucose molecule (glycolysis) into the matrix of the mitochondrion. There it is meet with acetyl CoA and CO2 and NADH2 is given off. The NADH2 goes straight to the E.T.C. to be used and this is not what happens in photosynthesis. After making 2 ATP, 6CO2, 8 NADH2 and 2 FADH2, the process finishes in the E.T.C. For every NADH2 dropping off its electrons there is energy to make 3 ATP. Only 2 are made from every FADH2 though. In summary, we breath so oxygen is the final electron acceptor and we exhale to alleviate wastes. In photosynthesis, there is a reaction center where there is a chlorophyll a and in photosystem I it is referred to as P700 and in photosystem II it is called P680. In photo. water is oxidized. The enzyme that differs
