During starvation, the body adapts to ensure that cells have access to a variety of fuel sources. Select all of the biochemical pathways that are active during periods of prolonged starvation.

Ketogenesis

Lipolysis

Proteolysis

Gluconeogenesis

Lipolysis

Gluconeogenesis

Ketogenesis

Explanation:

The physiological responses to starvation follows the below steps;

Change of carbohydrate metabolism to fat metabolism Glycogen stores are depleted Increase in gluconeogenesis occurs in 1 to 2 days of starvation Ketogenesis takes over due to decreased insulin levels Increased starvation from this step leads to protein catabolism and then organ failures
