During starvation, which of the following shows the most marked increase in plasma concentration?
|A||Free fatty acids|
a. Under fed conditions, glucose is the preferred fuel for most tissues. However, under starvation conditions, glucose must be reserved for use by the central nervous system.
b. There is a small initial decrease in plasma glucose upon starvation but the concentration levels off after a time because of conversion of glycogen in the liver.
c. Under starvation conditions, ketone bodies are made in the liver and provide a major metabolic fuel source for skeletal and heart muscle and can serve to meet some of the brain’s energy needs.
