Question

7. Which statement about insulin secretion is CORRECT Insulin release involves the export of calcium from the cytosol into the extracellular environment a. b. AGoes uptake, glucose binds allosteric sites in K channels deactivating the c. d. e. transporter Insulin is released from pancreatic alpha-cells Insulin release relies on glucose oxidation and oxidative phosphorylation. Insulin release is stimulated under exercise conditions. During starvation, glucagon stimulates lipolysis in white adipose tissue which is required to support ATP production by beta-oxidation in liver and muscle. True or False. 8. 9. Cirele the INCORRECT answer. ATP buffering in muscle involves: a. The storage of excess ATP in vesicles which is released during the fight or flight response b. The formation of phosphocreatine c. Creatine kinase in the cytosol. d. Transfer of the phosphate from ATP to creatine. e. The reversibility of the creatine/phosphocreatine reaction senses ATP demand and is required to stimulate lipogenesis when ATP is abundant. True or False.

Explanation / Answer

7. B

8. True as glucagon acts as catabolic hormone

9. Answer A

10. As AMP Kinase activation is the stimulation of ketogenesis, stimulation of skeletal muscle fatty acid oxidation and glucose uptake, lipogenesis & inhibition of adipocyte lipolysis
