MUSCLE PHYSIOLOGY

Detailed explanation-1: -Glycolysis occurs in both aerobic and anaerobic states. In aerobic conditions, pyruvate enters the citric acid cycle and undergoes oxidative phosphorylation leading to the net production of 32 ATP molecules. In anaerobic conditions, pyruvate converts to lactate through anaerobic glycolysis.

Detailed explanation-2: -The conversion of glucose to lactate is known as anaerobic glycolysis, since it does not require oxygen.

Detailed explanation-3: -Glycolysis is common to both aerobic and anaerobic respiration because glucose is the only source of energy and the process of glycolysis is independent of oxygen. Thus, the absence or presence of oxygen does not play a role in this process which is common to both aerobic and anaerobic respiration.

Detailed explanation-4: -Glucose breaks down without the presence of oxygen in anaerobic respiration. The chemical reaction transfers the energy from glucose to the cell. The final product varies depending on the metabolic pathway involved.

Detailed explanation-5: -The anaerobic glycolysis (lactic acid) system is dominant from about 10–30 seconds during a maximal effort. It replenishes very quickly over this period and produces 2 ATP molecules per glucose molecule, or about 5% of glucose’s energy potential (38 ATP molecules).
