Answer 1

Q30. Several hours after a meal, the brain uses glucose from glycogen stored in the liver as a fuel

During starvation, brain use ketone bodies produced in the liver for fuel.

Because the human brain can use ketone bodies as major fuel sources, the body is not forced to break down skeletal muscles at a high rate, thereby maintaining both cognitive function and mobility for up to several weeks
