Problem 51 Hard Difficulty

Diabetes results when either insulin cannot be produced or does not function properly. Consequently, diabetes can produce complications such as blindness, heart disease, and kidney disease. To help manage diabetes, a patient can get insulin injections. How do insulin injections promote a negative feedback loop to help maintain blood glucose production?
a. Insulin injections allow transport and storage of glucose to increase blood glucose levels after consuming a large or high-glucose meal.
b. Insulin injections allow only storage of glucose to decrease blood glucose levels after consuming
a large or high-glucose meal.
c. Insulin injections allow transport and storage of glucose to increase blood glucose levels before consuming a meal.
d. Insulin injections allow transport and storage of glucose to decrease blood glucose levels after consuming a large or high-glucose meal.

Hello, everyone, and welcome diabetes results when either insulin cannot be produced or does not function properly. Consequently, diabetes concludes complications such as blindness, heart disease and kidney disease help manage diabetes. A patient can get insulin injections. How do insulin injections promote a negative feedback loop to help maintain blood glucose production? Okay, so let's say that our baseline glucose levels that should be a healthy level would be right around here. But after a meal when we're just consumed, a lot of food are glucose levels are high, they're at this level. And so when we get the injection, when we got an insulin injection, let's say right over here, um, our blood glucose, I was actually drop back down to normal. And so it's a negative feedback loop because it restores it back to its original commission. Um, where's the positive feedback loop will keep amplifying the condition and making it like a cascading effect. So this is a negative feedback loop, and, um, it actually allows the in the wage to decreases. The blood group locals level in your blood stream is by allowing the transport and storage of glucose, which decreases the blood pools that was, um, after a meal. And so let's take a look at which of the, um, options. Ah, it says something similar. So, um parte de, um, Choice T says that insulin injections allowed the transport and storage of glucose to decrease the glucose levels after consuming a larger high glucose meal. And this brings it back down to its base land level. And it isn't negative feedback loop. So our answer is going to be D. Thank you for watching, and I hope this helped.
