AP PSYCHOLOGY

Detailed explanation-1: -Glucagon acts on the liver, causing glycogen to be broken down into glucose and released into the bloodstream, causing blood sugar levels to go back up. This reduces glucagon secretion and brings the system back to homeostasis.

Detailed explanation-2: -Homeostasis is maintained by a series of control mechanisms functioning at the organ, tissue or cellular level. These control mechanisms include substrate supply, activation or inhibition of individual enzymes and receptors, synthesis and degradation of enzymes, and compartmentalization.

Detailed explanation-3: -Insulin and glucagon are the two hormones primarily responsible for maintaining homeostasis of blood glucose levels. Additional regulation is mediated by the thyroid hormones.

Detailed explanation-4: -For example, to regulate temperature, you will sweat when you get too hot or shiver when you get too cold. Another way to think of it is like the thermostat in your house. Once set at a certain point, it works to keep the internal state at that level.
