Keep it Stable!
What is homeostasis?
The process by which organisms maintain a stable internal environment.
Stimulus: You are running very fast outside in hot weather.
Response: Your body releases sweat to cool down internal body temperature.
Which system regulates the release of our hormones?
Endocrine system.
How do hormones play a role in regulation?
By sending signals to target cells and organs, allowing the body to respond to changes and maintain homeostasis.
You eat a really big meal.
Blood-glucose levels rise, which signals to the pancreas to release insulin.
You haven't eaten all day, and your blood glucose level drops.
Your body releases glucagon.
Why do organisms need stability?
Cells function best within a narrow range of internal conditions. Maintaining stable conditions allows enzymes and other cellular processes to work properly, helping the organism survive.
Give an example of a stimulus and a response regarding humans maintaining homeostasis.
EX: Sweating from hot conditions.
Shivering from cold conditions.
Releasing insulin after eating.
Releasing ghrelin when hungry.
Hormones are classified as which macromolecule?
Proteins!
