1. The purpose of the Krebs cycle is to produce high energy carrier molecules like NADH and FADH2 that then feed into the electron transport chain. During this process, another by-product molecule is produced. Which molecule is produced during the Krebs cycle? Hint: the Krebs cycle is part of aerobic respiration. a. water b. carbon dioxide c. lipids d. glucose One of the end products of glycolysis is: fructose glucose carbon dioxide pyruvate The purpose of glycolysis and the Krebs cycle is to use split glucose to harness the energy in the bonds thereby generating high energy molecules that feed electrons into the electron transport chain. If an organisms has a defect in an electron chain molecule but can complete glycolysis, would the organism be able to survive? No, the organism would not be able to produce any energy
