Verified step by step guidance1
Understand that cellular respiration is a process that cells use to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and it involves multiple stages.
Identify the stages of cellular respiration: Glycolysis, Citric Acid Cycle (also known as Krebs Cycle), and Oxidative Phosphorylation (which includes the Electron Transport Chain).
Recognize that fermentation is an anaerobic process, meaning it does not require oxygen, and it occurs when oxygen is not available for cellular respiration.
Recall that glycolysis is the first stage of cellular respiration and occurs in the cytoplasm, where glucose is broken down into pyruvate, producing a small amount of ATP and NADH.
Understand that glycolysis is the only stage of cellular respiration that also occurs in fermentation, as it can proceed without oxygen, leading to either lactic acid fermentation or alcoholic fermentation depending on the organism.
