Detailed explanation-1: -Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.

Detailed explanation-2: -Cellular respiration is a series of chemical reactions that break down glucose to produce ATP, which may be used as energy to power many reactions throughout the body. There are three main steps of cellular respiration: glycolysis, the citric acid cycle, and oxidative phosphorylation.

Detailed explanation-3: -Glycolysis is the splitting, or lysis of glucose. Glycolysis converts the 6-carbon glucose into two 3-carbon pyruvate molecules. This process occurs in the cytoplasm of the cell, and it occurs in the presence or absence of oxygen. During glycolysis a small amount of NADH is made as are four ATP.

Detailed explanation-4: -Most of the steps in the cellular respiration process take place in the mitochondria. A series or chain of chemical reactions is involved in the complex breakdown of glucose. The ultimate aim of cellular respiration is to completely break the carbon-carbon (C-C) bond of the glucose to release energy (ATP).

Detailed explanation-5: -Key points. Respiration is a chemical reaction which occurs in all living cells, releasing energy from glucose. Aerobic respiration occurs with oxygen and releases more energy but more slowly. Anaerobic respiration occurs without oxygen and releases less energy but more quickly.
