Which hormone is primarily responsible for lowering blood glucose levels to maintain homeostasis in humans?
A
Adrenaline
B
Glucagon
C
Insulin
D
Cortisol
Verified step by step guidance1
Step 1: Understand the concept of homeostasis, which refers to the body's ability to maintain stable internal conditions, including blood glucose levels.
Step 2: Learn about the role of hormones in regulating blood glucose levels. Insulin is a hormone produced by the pancreas that helps lower blood glucose levels by facilitating the uptake of glucose into cells and promoting its storage as glycogen in the liver.
Step 3: Compare the functions of the other hormones listed in the problem: Adrenaline (increases blood glucose during stress), Glucagon (raises blood glucose by stimulating glycogen breakdown), and Cortisol (increases blood glucose during prolonged stress).
Step 4: Recognize that insulin is the primary hormone responsible for lowering blood glucose levels to maintain homeostasis, as opposed to the other hormones, which generally increase blood glucose levels.
Step 5: Conclude that the correct answer is insulin, based on its unique role in reducing blood glucose levels and maintaining homeostasis in humans.
