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: -Glycolysis is the initial breakdown of glucose to pyruvate, a three carbon structure, in the cytoplasm. The pyruvate then moves into the mitochondrial matrix where a transition step called pyruvate oxidation takes place.
Detailed explanation-3: -Answer and Explanation: Cellular respiration is best described as E) changing of stored chemical energy in food molecules to a form usable by organisms.
Detailed explanation-4: -Glycolysis is a series of reactions that extract energy from glucose by splitting it into two three-carbon molecules called pyruvates.
Detailed explanation-5: -Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP . Generally speaking, this three-stage process involves glucose and oxygen reacting to form carbon dioxide and water.
