Solution

To answer the question regarding the substances that play a key role in hunger, eating, and satiety, let’s analyze each option:

  1. Testosterone: Primarily known as a male sex hormone, it is not directly involved in regulating hunger or satiety.
  2. Insulin: This hormone is crucial for glucose metabolism and helps to signal satiety after eating by promoting glucose uptake and storage.
  3. Leptin: A hormone produced by adipose (fat) tissue, it plays a significant role in regulating energy balance by inhibiting hunger, which in turn helps to regulate body weight.
  4. Glucose: While glucose levels can influence hunger sensations (as low levels may stimulate appetite), it's not a hormone itself but rather a molecule that can affect satiety indirectly.
  5. Cortisol: Known as the stress hormone, cortisol can influence eating behaviors and appetite, especially during stress but is not a primary regulator of satiety.

Final Answer

The three substances that play a key role in hunger, eating, and satiety are insulin, leptin, and cortisol.
