Detailed explanation-1: -The reactions of cellular respiration can be grouped into three stages: glycolysis (stage 1), the Krebs cycle, also called the citric acid cycle (stage 2), and electron transport (stage 3).

Detailed explanation-2: -The second stage of cellular respiration is the citric acid cycle. It is also commonly referred to as the Krebs cycle after the researcher who discovered it. In this stage, Acetyl Coenzyme A is converted to carbon dioxide via two decarboxylation reactions.

Detailed explanation-3: -Aerobic respiration involves four stages: glycolysis, a transition reaction that forms acetyl coenzyme A, the citric acid (Krebs) cycle, and an electron transport chain and chemiosmosis.

Detailed explanation-4: -There are three main steps of cellular respiration: glycolysis, the citric acid cycle, and oxidative phosphorylation. Glycolysis takes place in the cytosol, the citric acid cycle occurs in the mitochondrial matrix, and oxidative phosphorylation occurs on the inner mitochondrial membrane.

Detailed explanation-5: -There are four stages: glycolysis, the link reaction, the Krebs cycle and oxidative phosphorylation. During glycolysis, glucose molecules (six-carbon molecules) are split into two pyruvates (three-carbon molecules) during a sequence of enzyme-controlled reactions. This occurs in both aerobic and anaerobic respiration.
