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: -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-3: -Glycolysis is a process in which glucose is broken down to pyruvic acid without the help of an external electron acceptor such as oxygen. It occurs in the cell cytoplasm and so is common to both aerobic and anaerobic organisms.

Detailed explanation-4: -Glycolysis (see “Glycolysis” concept) is an anaerobic process-it does not need oxygen to proceed. This process produces a minimal amount of ATP. The Krebs cycle and electron transport do need oxygen to proceed, and in the presence of oxygen, these process produce much more ATP than glycolysis alone.

Detailed explanation-5: -Anaerobic glycolysis is the transformation of glucose to lactate when limited amounts of oxygen (O2) are available. Anaerobic glycolysis is only an effective means of energy production during short, intense exercise, providing energy for a period ranging from 10 seconds to 2 minutes.
