Detailed explanation-1: -Adenosine triphosphate (ATP) is the source of energy for use and storage at the cellular level. The structure of ATP is a nucleoside triphosphate, consisting of a nitrogenous base (adenine), a ribose sugar, and three serially bonded phosphate groups.

Detailed explanation-2: -So, in aerobic respiration, a total of 38 molecules of ATP are created, with 2 ATP molecules formed outside the mitochondria. Electron transfer from glycolysis’ NADH and FADH2 molecules, pyruvate transformation, and the Krebs cycle generates up to 32 additional ATP molecules.

Detailed explanation-3: -ATP stands for Adenosine Triphosphate and it is the energy currency of the cell. The hydrolysis of one molecule of ATP to Adenosine Diphosphate ADP and inorganic phosphate releases 7.3 kcal /mol of energy.

Detailed explanation-4: -Functions of ATP The ATP is used for various cellular functions, including transportation of different molecules across cell membranes. Other functions of ATP include supplying the energy required for the muscle contraction, circulation of blood, locomotion and various body movements.

Detailed explanation-5: -So the average cell in the human body produces ∼107–108 ATP/s, roughly consistent with the estimate of the energetic cost of protein turnover and several orders of magnitude more energy than we estimated that keratocyte motility requires.
