HUMAN NUTRITION

Detailed explanation-1: -The body has three primary ways of creating energy. These physiological pathways are called energy systems. The anaerobic energy system (also called the lactic acid system) is the body’s way of creating energy in the form of ATP quickly.

Detailed explanation-2: -The lactic acid system is an anaerobic ener-gy system in which the high-energy compound adenosintriphosphate (ATP) is manufactured from the breakdown of glucose to pyruvic acid in the muscle cells.

Detailed explanation-3: -When the ATP and PC stores have run out the energy the body needs is provided by the lactic acid system. This system relies on the breakdown of glucose (from carbohydrates) which has been stored in the muscles as glycogen.

Detailed explanation-4: -Aerobic glycolysis (Warburg effect) is one of the hallmarks of cancer metabolism, and it implies an excessive production of protons, which if remaining inside the cell would result in fatal intracellular acidosis.
