During starvation, which of the following shows the most marked increase in plasma concentration?



A Free fatty acids
B Glucose

C Glycogen
D Ketone bodies

Ans. D Ketone bodies

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.
