Which of the following would you expect to see when blood glucose levels become low due to skipping lunch?

a. increased brain reliance on fatty acids for energy
b. increased activity of hormone sensitive lipase
c. increased activity of glycogen synthase
d. increased secretion from beta cells
e. more than one of the above

e. more than one of the above

Explanation:

Skipping lunch leads to starvation leads to a decrease in blood glucose level and low energy levels.  

This lack of glucose increases metabolism of reserved fat for energy production. There is an increased oxidation of fatty acids stored in the liver which leads to increased production of ketone bodies from acetyl CoA. Brain metabolism also follows the same path where fatty acids are converted to ketone bodies.  

Further, impaired insulin secretion from beta cells and elevation of epinephrine during starvation activates hormone-sensitive lipase

The activity of glycogen synthase is also increased during starvation due to increased glycogen metabolism.

However, insulin secretion is affected due to starvation.
