Answer: Catabolism
Explanation:
When the body's minimum caloric intake for the day is not met and it needs to keep on functioning, catabolism will kick in. Catabolism is a process in which organic nutrients such as polysaccharides, proteins and fatty acids are transformed into energy.
For fat to be useful as a source of energy, hydrolysis has to break down the triglycerides first and then the fatty acids we have as an outcome of that process will be fund oxidized.
