MUSCLE PHYSIOLOGY

Detailed explanation-1: -Fermentation is another anaerobic (non-oxygen-requiring) pathway for breaking down glucose, one that’s performed by many types of organisms and cells. In fermentation, the only energy extraction pathway is glycolysis, with one or two extra reactions tacked on at the end.

Detailed explanation-2: -Metabolism involves either using energy to build organic molecules or breaking down organic molecules in which energy is stored. Organic molecules contain carbon. Therefore, an organism’s metabolism is part of Earth’s carbon cycle.

Detailed explanation-3: -The anaerobic process takes place in yeast at the time of fermentation. The microbes like yeast dissociate the food, that is, glucose into carbon dioxide, and ethanol, and discharge energy in the absence of oxygen.

Detailed explanation-4: -Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP . Generally speaking, this three-stage process involves glucose and oxygen reacting to form carbon dioxide and water.
