How do the release of glucagon and insulin and the processes they cause help maintain homeostasis in the body?
Understand the Problem
The question is asking how the release of glucagon and insulin, along with the processes they cause, contribute to maintaining homeostasis in the body. In essence, it's asking about the roles of these hormones in regulating physiological balance.
Answer
Glucagon and insulin maintain blood sugar homeostasis through a negative feedback loop. Insulin lowers blood sugar, while glucagon raises it.
Glucagon and insulin work together in a negative feedback loop to maintain blood sugar homeostasis. When blood sugar is high, insulin is released, allowing glucose to enter cells and be stored as glycogen in the liver, reducing blood sugar levels. When blood sugar is low, glucagon is released, signaling the liver to convert glycogen back into glucose and release it into the blood, increasing blood sugar levels.
Answer for screen readers
Glucagon and insulin work together in a negative feedback loop to maintain blood sugar homeostasis. When blood sugar is high, insulin is released, allowing glucose to enter cells and be stored as glycogen in the liver, reducing blood sugar levels. When blood sugar is low, glucagon is released, signaling the liver to convert glycogen back into glucose and release it into the blood, increasing blood sugar levels.
More Information
The balance between insulin and glucagon is crucial for maintaining stable blood sugar levels, which is essential for providing cells with a constant supply of energy and preventing damage caused by high or low blood sugar.
Tips
A common mistake is thinking that insulin and glucagon have the same effect on blood sugar. Remember, they have opposite effects and work together to maintain balance.
