When enzyme and substrate combine, substrate is transformed and enzyme is recovered. Operate at optimum temperature and pH 5. Reaction is controlled by feedback inhibition - End product inhibits an enzyme s activity in the pathway. Each time a substance is oxidized another is reduced. Used in oxidation reduction reactions.
Energy is released during a cell s oxidation of glucose.
B. Generation of ATP 1. Stored as ATP until needed. Biochemical Pathways of Energy Production A. Description - Series of enzymatically catalyzed reactions called biochemical pathways store energy in and release energy from organic molecules. B. Carbohydrate Metabolism 1. Most of a cell s energy is produced from the oxidation of carbohydrate - Most commonly glucose 2.
