Final answer:
The false statement regarding set point, fat cells, and obesity is that leptin tells your brain to eat more, whereas it actually signals satiety. Leptin resistance in obesity causes the brain to not register these signals effectively. so, option d is the correct answer.
Step-by-step explanation:
Regarding the set point, fat cells, and obesity, the statement that is FALSE is: d. Leptin is released from fat cells and tells your brain that you need to eat more. This statement is incorrect because, in reality, leptin is a hormone that signals satiety, not hunger. When leptin is released from the fat cells, it communicates to the brain that the body has sufficient energy stored and there is no need to eat more. It is when leptin levels are low that the brain receives a signal to increase food intake. On the contrary, in cases of obesity, individuals may develop leptin resistance where despite high levels of the hormone, the brain does not properly receive the satiety signal, leading to increased food intake and weight gain.
The FALSE statement regarding the set point, fat cells, and obesity is d. Leptin is released from fat cells and tells your brain that you need to eat more.
Leptin is actually released from fat cells and helps to regulate appetite based on the body's fat reserves. When fat reserves are high, more leptin is secreted and appetite is inhibited, so you eat less. In obesity, decreased sensitivity to leptin occurs, resulting in an inability to detect satiety despite high-fat reserves, leading people to overeat and gain more weight.
