Question

3 20 The conversion pyruvate to either ethanol or lactate occurs A. when there is an abundance of pyruvate but a deficiency of onygen B. when there is an abundance of BOTH pyruvate and oxygen C. when there is a deficiency of BOTH pyruvate and oxygen D. for the regeneration of NADH so that hydrolysis of ATP can continue to fuel the glycolysis pathway Explain how gluconeogenesis differs from gtycolysis 21 Gluconeogenesis is simply the reverse of all 10 steps of glycolysis: TRUE or FALSE Describe how the manufocture and breokdown of glycoge 22 Which kind of a process is 23. Glycogenesis will occur en are related to glycolysis and gluconeogenesis glycogenolysis? A catabolic 8. anabolic C.hydrolysis D. redox A. 8. when oxygen levels are low when oxygen levels are high C. when blood glucose levels are low D. when blood glucose levels are high Give an overview of the citric ocid cycle and explain how it is controlled chain to helç 24. NAD is reduced to NADH during the citric acid cycle and then travels to the electron transport chain to produce ATP. TRUE or FALSE Which of the following is both the end product and an initial substrate of the citric acid cycle? 25. A citrate B. pyruvate C a-ketoglutarate D. oxaloacetate Describe how the products of the citric acid cycle are used by the electron transport chain and oxidative 26 Electrons pass through the electron transport chain via transfer from one coenzyme to the next and finally reduce O2 to H:O. TRUE or FALSE 27 The movement of H' through ATP synthase during oxidative phosphorylation is an example of A passive diffusion b. active transport c. osmosis d. facilitated diffusion Describe the catabolism of triglycerides, the β-oxidation spiral, and how the β-oxidation spiral differs from fatty acid biosynthesis 28.
