MUSCLE PHYSIOLOGY

Detailed explanation-1: -Photophosphorylation is a biochemical process that involves the addition of phosphate to an organic compound. Few examples are, addition of phosphate group to ADP to form ATP, an addition of phosphate group to glucose to form glucose-6-phosphate.

Detailed explanation-2: -Phosphorylation of ADP is the formation of ATP molecule utilizing the energy produced by proton motive force at the ATP synthase complex. So, the correct answer is ‘There is an addition of a phosphate to ADP, creating ATP’

Detailed explanation-3: -Oxidative phosphorylation is the production of ATP using energy derived from the transfer of electrons in an electron transport system and occurs by chemiosmosis. An atom of hydrogen contains only one proton (H+) and one electron. Electrons have stored energy, or potential energy, ready to do work.

Detailed explanation-4: -ATP is able to power cellular processes by transferring a phosphate group to another molecule (a process called phosphorylation).
