**Core Concept**
In starvation, the body undergoes a series of metabolic changes to maintain energy homeostasis. This includes the breakdown of stored energy sources, such as glycogen and fat, and the mobilization of glucose from non-carbohydrate sources.
**Why the Correct Answer is Right**
During starvation, the body's insulin levels decrease, and glucagon levels increase. This leads to the breakdown of glycogen to glucose through glycogenolysis, and the release of glucose from non-carbohydrate sources such as lactate, glycerol, and amino acids through gluconeogenesis. The liver plays a crucial role in this process, producing glucose through gluconeogenesis and releasing it into the bloodstream.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not accurately describe a metabolic change seen in starvation.
**Option B:** This option is incorrect because it does not accurately describe a metabolic change seen in starvation.
**Option C:** This option is incorrect because it does not accurately describe a metabolic change seen in starvation.
**Clinical Pearl / High-Yield Fact**
One important fact to remember is that gluconeogenesis is the primary mechanism by which the body maintains blood glucose levels during starvation. This process is essential for maintaining energy homeostasis and preventing hypoglycemia.
**Correct Answer:** C.
