Substrate-level Phosphorylation and Oxidative Phosphorylation

WebPhotosynthesis occurs in two stages: the light-dependent stage, which takes place in the thylakoids, and the light-independent stage, which takes place in the stroma. Light energy is used to breakdown water (photolysis) to produce hydrogen ions, electrons and oxygen in the thylakoid lumen. A proton gradient is formed due to the photolysis of ... WebPhosphorylation reactions involve the addition of a phosphate group to another molecule. Correct Statements: -One of the substrates is a molecule derived from the breakdown of glucose -An enzyme is required in order for the reaction to occur -A bond must be broken between an organic molecule and phosphate before ATP can form.
