Which of the following does not increase satiety or suppress hunger?

Question

BlackTom AI · Accepted Answer

To tackle the question, let's examine what each option represents in the context of appetite and satiety signals.
Option 1: leptin. Leptin is a hormone produced by fat cells that signals energy sufficiency to the brain and tends to promote satiety, reducing food intake over time. This option describes a molecule that generally increases fullness rather than hunger, so it would contribute to suppressing appetite.
Option 2: cholecystokinin (CCK). CCK is released after a meal, particularly in response to fats and proteins, and it slows gastric emptying while signaling fullness to the brain. This leads to increased satiety and decreased appetite, making it act to suppress hunger.
Option 3: serotonin. Serotonin, a neurotransmitter involved in mood and appetite regulation, also plays a role in promoting satiety and reducing meal size in many circumstances. Elevated serotonergic activity is associated with suppressed appetite, so it supports fullness rather than hunger.
Option 4: ghrelin. Ghrelin is known as the hunger hormone because it rises before meals and stimulates appetite, promoting food intake. It is the primary signal that increases hunger, opposite to satiety-promoting signals discussed in the other options.
In summary, the first three options (leptin, cholecystokinin, and serotonin) are associated with increasing satiety or reducing hunger, whereas ghrelin increases hunger. The question asks for the member that does not increase satiety or suppress hunger, which points to ghrelin as the mismatched option.
