(6 POINTS) In cellular respiration, phosphorylation occurs during glycolysis and the citric acid cycle, whereas phosphorylation occurs as a result of the electron transport chain. In cellular respiration is actively pumped from the to the , whereas in photosynthesis is actively pumped from the to the In both cellular respiration and photosynthesis, the flow of _down its concentration gradient occurs through the complex which produces energy by converting,

Answer 1

b= Activation energy of catalyzed reaction 327 HU C = Activation energy of Uncatalyzed reaction d = change in free energy The substrate needs some energy to get activated. for a chemical reaction. The minimum energy which is required for a reaction to raise the energy of molecules is called activation energy . Enzymes in a reaction decrease the level of activation energy and increase the rate of formation of product!

33. In cellular respiration substrate level phosphorylation occurs during glycolysis and the citric acid cycle,where as oxidative phosphorylation occurs as a result of the electron transport chain.

In cellular respiration H+ is actively pumped from the matrix to the intercellular space ,where as in photosynthesis H+ is actively pumped from the stroma to thylakoid lumen.

In both cellular respiration and photosynthesis,the flow of H+ down it's concentration gradient occurs through the cytochrome complex which produces energy by converting ADP to ATP.

Explanation- Substrate level phosphorylation occurs in presence of light. It converts ATP from ADP and inorganic phosphate. It happens in chloroplast. Oxidative phosphoration occurs in mitochondria. Here ATP is formed by oxidation reduction reactions during electron transport Chain. Oxygen acts as a hydrogen acceptor. In photosynthesis cytochrome complex lies between psI and psII. In cellular respiration,cytochrome complex present in complex IV of electron transport chain.
