However, when these mice fast or exercise, their blood glucose drops dangerously. Which hypothesis best explains their problem? (Explain your choice.)
a. The mice have insulin-dependent diabetes.
b. The mice lack insulin receptors on their cells.
c. The mice lack glucagon receptors on their cells.

Question

A strain of mice remains healthy as long as they are fed regularly. After they eat, their blood glucose level rises slightly and then declines to a homeostatic level. However, when these mice fast or exercise, their blood glucose drops dangerously. Which hypothesis best explains their problem? (Explain your choice.)

a. The mice have insulin-dependent diabetes.

b. The mice lack insulin receptors on their cells.

c. The mice lack glucagon receptors on their cells.

d. The mice cannot synthesize glycogen from glucose.

Accepted Answer

Hey everyone, let's take a look at this question together, identify which of the following is not a function of insulin. Let's recall what we've learned about insulin and the purpose of insulin in the body. But when we're talking about insulin we know that its main function is to lower blood glucose levels. And so insulin has to do with the blood sugar levels in our body and it lowers those blood glucose levels now. How does insulin do that? Well, we know that it stimulates the process of like oh genesis which we know that glycogen icis is the process by which we store those excess glucose so that we can use it at a later point in time. And we also know that insulin inhibits two pathways which are like oh you know like this which we know that glycogen analysis is the pathway where glycogen breaks down into that glucose one, phosphate and glucose. And then we also know it inhibits glucose. Oh the genesis which we know is the process of synthesizing new glucose, which we can break down from the part of the word neo So leuco the A genesis is the synthesis of new glucose. And coincidentally by writing what we know that insulin does. We can look at our answer choices and C. Answer choice A. It lowers blood glucose levels which we do know it does. So that means that answer choice A. Is a function of insulin and not the correct answer and answer choice B. It stimulates like a genesis which we know that it actually does stimulate like a genesis. And so answer choice B is a function of insulin, which means that it is not the correct answer. And answer choice C says it stimulates glucose neurogenesis, which we know that insulin actually inhibits glue konia genesis because it doesn't want to make new glucose molecules. And so answer choice C is a possible answer. Since it is not a function of insulin and then answer choice D. It inhibits like oh, general ISis, which we do know, it inhibits that like oh, gina license process. So answer choice D. Is a function of insulin may, making it not the correct answer. So that means answer Choice C is the only correct answer here. Because we know that insulin actually inhibits glucose neurogenesis because insulin does not want to synthesize new glucose molecules. So, answer choice C is the only one here that is not a function of insulin. Hope you found this video to be helpful. Thank you and goodbye.
