Detailed explanation-1: -The three stages of aerobic cellular respiration are glycolysis (an anaerobic process), the Krebs cycle, and oxidative phosphorylation.

Detailed explanation-2: -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.

Detailed explanation-3: -The second stage of aerobic respiration is the Kreb’s cycle, which is also called the citric acid cycle. Glycolysis took place in the cytoplasm, but afterwards the pyruvate molecules move into the mitochondria, which is where the Kreb’s cycle takes place.

Detailed explanation-4: -What are the main steps of cellular respiration? There are three main steps of cellular respiration: glycolysis; the citric acid (TCA) or the Krebs cycle; and the electron transport chain, where oxidative phosphorylation occurs.

Detailed explanation-5: -The second stage of cellular respiration is the transfer of the energy in pyruvate, which is the energy initially in glucose, into two energy carriers, NADH and FADH2. A small amount of ATP is also made during this process.
