There are three main stages of cellular respiration: glycolysis, the citric acid cycle, and electron transport/oxidative phosphorylation.
Glycolysis is the first step of cellular respiration, the process by which living cells break down glucose into small, energy-containing molecules called ATP. In glycolysis, a single glucose molecule breaks down into two molecules of pyruvate, which can then be broken down further to release ATP.
