Leptin is a chemical secreted by fat cells and recognized in the brain as a signal of satiety. It has been shown in laboratory experiments that if leptin receptors in the hypothalamus are blocked, then the animal will: A Avoid novel foods B Be unable to break down carbohydrates into glucose C Eat excessively and develop obesity D Gradually starve to death E Suffer from low blood sugar levels

Key Concept

Leptin is a hormone that regulates appetite and energy balance by signaling satiety to the brain.

Explanation

Leptin is secreted by fat cells and acts on receptors in the hypothalamus of the brain. When leptin receptors in the hypothalamus are blocked, the brain does not receive the signal of satiety, leading to excessive eating and the development of obesity. Therefore, the correct answer is C - Eat excessively and develop obesity.
