Question

1. every time you eat, a negative - feedback mechanism controls the level of sugar in your blood. the main sugar found in your blood is glucose. after you eat something, your body absorbs the glucose from your intestine and deposits it into your blood.
2. this increases the concentration of glucose and stimulates your pancreas to release a chemical called insulin. insulin is a cellular - signaling molecule that tells muscle and liver cells to take up glucose. liver cells store the extra glucose as glycogen, a chain of glucose used as a storage product.
3. muscle cells can store glucose or use it to make atp and contract. as this process happens, glucose concentrations are lowered in the blood. glucose is the main signal for the pancreas to produce insulin. when it, the pancreas stops producing insulin, and the cells stop taking up glucose.
4. thus, glucose levels are maintained in a specific range, and the rest of the body has access to glucose consistently.

question: is this a negative or positive feedback loop?
this is a positive feedback loop
this is a negative feedback loop
this is a neutral feedback loop

Explanation:

In a negative - feedback loop, the body's response counteracts the initial change. When blood glucose levels rise after eating, insulin is released to lower them back to normal. This opposes the initial increase in glucose, which is characteristic of a negative - feedback mechanism. In a positive - feedback loop, the response would amplify the initial change.

Answer:

This is a negative feedback loop.
