Question

Which of the following is associated with the release of insulin from the pancreas? Choose One A.) Liver glycogen phosphorylase is activated. B.) Gluconeogenesis is activated and glycolysis is inhibited. C.) The production of mevalonate decreases D.) Acetyl-CoA levels rise and ketone body synthesis increases. E.) Oxaloacetate levels are high and citrate synthesis increases.

In humans, the Cori cycle involves the coordinated function of different metabolic pathways in two tissues, the liver and skeletal muscle. Which of the following pairs of enzyme activities accurately reflects the metabolism that takes place in each tissue during the Cori cycle? Choose One A.) glycogen phosphorylase in the liver and glycogen synthase in the skeletal muscle B.) hexokinase in the liver and lactate dehydrogenase in the skeletal muscle C.) glucose 6-phosphatase in liver and lactate dehydrogenase in skeletal muscle D.) glucose 6-phosphatase in liver and fructose 1,6-bisphosphatase in skeletal muscle E.) alcohol dehydrogenase in the liver and phosphofructokinase-1 in the skeletal muscle

Explanation / Answer

1)Acetyl-CoA levels rise and ketone body synthesis increases

because insulin is linked to acetyl -Coa leading to keton synthesis in future.

2) C.) glucose 6-phosphatase in liver and lactate dehydrogenase in skeletal muscle

as glucose 6 phosphate is formed in liver.
