Question

What are the answers for 16 and 17 please help

Answer 1

I took Bio last semester but
Glucose is sugar, the monomer (building block) of carbohydrates. The body stores glucose in the bloodstream, to carry around to cells for quick and easy energy. When there is too much sugar the pancreas secretes insulin, a hormone it creates to regulate the sugar. When glucose levels start decreasing, the insulin decreases as well, I guess kind of like “okay the sugar is going down over there, we don’t need as much insulin to control it anymore.” So I’m other words, when your blood sugar is high, your pancreas secretes insulin to regulate it. When glucose is really low in your body, that’s when glucagon is released, to make sure your glucose doesn’t drop too low.
The maintenance of blood sugar is vital to an organisms existence. Without glucagon, your blood sugar plummets. Without insulin, your blood sugar skyrockets. And this can be detrimental to your body, if you don’t have these hormones. There are medical issues related to the imbalance of these hormones, such as type 1 diabetes, which results in a lack of insulin. People with type 1 diabetes have pancreases (pancrei?) that don’t produce enough insulin to maintain a healthy level of blood sugar.
So the feedback topic... I read a bit about it because I didn’t learn about this, but for number 17, I think that this would be negative feedback, because you’re regulating the blood sugar levels... it’s good to have balance. Anyway, I hope this helped a little.
