• When the bond present between the two phosphate groups breaks down, it releases energy.
• In a living cell, energy is released to perform many essential metabolic activities; the process is called respiration.
Further Explanation:
Respiration is a biochemical reaction that breaks down the molecule of glucose and then produces ATP. The different stages of cellular respiration are:
• Glycolysis
• Pyruvate oxidation
• Krebs cycle
• Oxidative phosphorylation
Glycolysis converts the glucose molecules to pyruvate molecules, and it is the initial step of cellular respiration. It can occur in the present as well as in the absence of oxygen. This process converts glucose molecules to pyruvate molecules. During this process, there is a net release of ATP (produce energy in a living cell) and NADH molecules.
The ATP is synthesized due to the occurrence of a proton gradient across the inner membrane of mitochondria. Synthesis of ATP is possible in the membrane only if the proton gradient is well established; any leakage in the membrane will disturb the gradient and directly affect the ATP synthesis.ATP consists of three phosphate groups; when the bond between the phosphate groups breakdowns, it releases energy. The energy released in the body help in metabolic activity.
