Unformatted text preview: glycolysis is the sole source of energy. It is a somewhat inefficient process because much of the cellular energy remains in the two molecules of pyruvic acid. The Krebs cycle. Following glycolysis, the mechanism of cellular respiration then involves another multistep process called the Krebs cycle , also called the citric acid cycle and the tricarboxylic acid cycle.
