What will most likely happen if a person does not consume the minimum daily requirement of carbohydrates? a. the body will break down chitin from the bones. b. the body will break down glycogen from the liver. c. the body will break down glucose from the blood. d. the body will break down galactose from the pancreas.

Answer;

The body will break down glycogen from the liver.

Explanation;

-To attain the minimum daily requirement of carbohydrates, the body is stimulated to break down glycogen to produce glucose. This is dome by producing glucagon a hormone which breaks down glycogen stored in the liver.

-In humans, glycogen is made and stored in liver and muscle cells. Muscle cell glycogen is broken down into glucose, and liver glycogen is broken down into glucose as a circulating energy source glucose for use by the body.

The body will break down glycogen from the liver if the person does not consume minimum daily requirement of carbohydrate.

Further Explanation:

Glycogen is a branched carbon polymer of glucose which is break down to release energy when minimum requirement of the carbohydrate is not consumed. Glycogen is the main fuel which is break down into glucose and glucose is the important fuel used by the brain during prolonged starvation. Glycogen also called primary carbohydrate is mainly stored in liver and skeletal muscle. Liver is the main storage organ but skeletal muscle obtains the maximum amount of it because of their large mass.

Glycogenolysis is the method by which the primary carbohydrate breaks down into glucose to release instant energy and helps in maintaining blood glucose level during prolonged starvation or fasting. The release of energy is stimulated by two hormone; glucagon and epinephrine (adrenaline).

Glucagon is secreted by pancreas which helps in maintaining the blood glucose level whereas epinephrine or adrenaline is secreted by adrenal gland present above the kidney which is instigated by flight or fight response. It helps in stimulating glycogen by indicating physiological reduction in blood glucose level.
