Document Summary
Anaerobic respiration and fermentation: what is anaerobic respiration and fermentation, two processes evolved to enable cells to produce atp without using oxygen, both less efficient than aerobic respiration. Anaerobic respiration uses a molecule other than oxygen as the final electron. In fermentation, electrons are transferred to an organic molecule rather than to an. Interrelationships of catabolic and anabolic pathways: let"s use other sugars!! Carbohydrates, fats, and proteins can serve as electron sources for oxidative. Glycolysis and citric acid cycle stages of cellular respiration are regulated by. If atp is abundant, cellular respiration slows down, conserving resources, allowing intermediates to be used in biosynthesis. If atp concentration is low, cellular respiration increases to compensate. 2: =allosteric regulation by feedback inhibition, reversible binding of regulatory molecule to a site on enzyme to either increase/decrease enzyme activity, glycolysis feedback mechanisms, key enzyme= phosphofructokinase, hexokinase, pyruvate kinase a)
