Question 2) The major energy sources for non-nervous tissue during the postabsorptive period are fatty acids and ketones.
Indicate whether the statement is true or false.

Question 3) Insulin has no effect on the carrier-mediated transport of glucose in the liver; therefore, insulin does not stimulate the uptake of glucose by that organ.
Indicate whether the statement is true or false.

Question 4) Insulin inhibits the enzymes in the liver that catalyze reactions leading to gluconeogenesis.
Indicate whether the statement is true or false.

Question 5) The metabolic events characteristic of the absorptive state can be attributed to the presence of large amounts of insulin in the blood, whereas the events of the postabsorptive state can be attributed largely to decreased insulin levels.
Indicate whether the statement is true or false.

Question 8) Most of the triglycerides absorbed as chylomicrons are ultimately stored as fat in the adipose tissue.
Indicate whether the statement is true or false.
