Skeletal muscle relies primarily on which glucose source during exercise?     from liver gluconeogenesis     does not discriminate between sources of glucose     from liver glycogenolysis     from muscle glycogenolysis

1. Myasthenia Gravis is a disease in which the patients have a deficiency of ACh receptors in their skeletal muscles, The result is a weakening of muscle function, How and why would the administartion of an acetylcholinesterase inhibitor (AChEl) improve muscle function in these patients?  2. List and describe the distinctly functions of ATP during muscle contractions.

Which of the following processes do NOT produce CO2? (1) Fatty acid synthesis (2) Oxidative deamination (3) Preparatory phase of glycolysis (4) Pentose phosphate pathway A. (1) and (2) only B. (2) and (3) only C. (2) and (4) only D. (1), (3) and (4) only E. (1), (2), (3) and (4) 11. is an intermediate metabolite linkage between carbohydrate and fat metabolism. A. Malate B. Citrate C. Acetyl-CoA D. Aspartate E. a-ketoglutarate 12. transfers carnitine from mitochondrial matrix to cytoplasm during the transport of fatty acid to mitochondria. A. Carnitine acyltransferase I B. Carnitine acyltransferase II C. Transaminase D. Translocase E. Citric acid shuttle 13. Which of the following reactions/ pathways does NOT produce NADH? A. Payoff phase of glycolysis B. Oxidative deamination of glutamine C. B-oxidation…

5. Which of the following is NOT an expected result of anaerobic training?     increased muscle strength     enhanced maximal oxygen consumption     improved tolerance for pH imbalance     enhanced short-term, high-intensity exercise capacity
