Answer

Brief Explanations:

Glycolysis is the first stage of cellular respiration. In this process, one molecule of glucose (a 6 - carbon molecule) is broken down into two molecules of pyruvic acid (a 3 - carbon molecule). The electron transport chain is mainly involved in generating a large amount of ATP using the energy from electrons. The Krebs cycle (citric acid cycle) further oxidizes acetyl - CoA (derived from pyruvic acid) to release more energy. Acetyl - CoA formation is the step where pyruvic acid is converted to acetyl - CoA (after glycolysis).
