Question 3 • Biology

If a person did not eat for several days, which sequence of events would occur?

Answer
A
Proteins stores would be depleted first, then stored lipids, and then stored glycogen.
B
Lipid stores would be depleted first, then stored glycogen, and then structural proteins.
C
Glycogen stores would be depleted first, then stored lipids, and then structural proteins.
D
Glycogen stores would be depleted first, then structural proteins, and then stored lipids.

Explanation

During fasting, the body first uses its limited glycogen stores to help maintain blood glucose. As glycogen runs low, it relies more on stored lipids for energy, while also breaking down some protein later in prolonged starvation. Structural proteins are therefore used after glycogen and fat stores, matching the sequence in choice C.
