Biology 121 Organismal Biology

This program outlines the essential roles of aerobic and anaerobic respiration and discusses respiration's vital role in all living cells. It explores energy sources for living organisms, endergonic and exergonic chemical reactions, and the role of ATP as energy carrier. Differentiating between aerobic and anaerobic processes, the program illustrates the stages of aerobic respiration, showing glycolysis, the Krebs cycle, and the electron transport chain. It also looks at anaerobic respiration in animals, plants, and yeasts and discusses energy transformations. 25 minutes
