Major metabolic fuel for hea in starvation is
Correct Answer: Ketone bodies
Description: The liver has a greater capacity for b-oxidation than is required to meet its own energy needs, and as fasting becomes more prolonged, it forms more acetyl-CoA than can be oxidized. This acetyl-CoA is used to synthesize the ketone bodies which are major metabolic fuels for skeletal and hea muscle and can meet up to 20% of the brain's energy needs. In prolonged starvation, glucose may represent less than 10% of whole body energy-yielding metabolism. Reference: Harper; 30th edition; Chapter 14; Page no: 148
