The level of glucose in the bloodstream drops. The person requires glucose in cells to meet the demand for ATP (glucose is broken down to create ATP). The body detects glucose levels with a particular receptor designed for this function. These receptors release hormones, chemical messages that initiate the start of the feedback mechanism. The hormones travel to their target tissue and initiate a corrective response. In this case, the corrective response is the secretion of more glucose into the bloodstream. Does this demonstrate POSITIVE or NEGATIVE FEEDBACK?

It is negative feedback because the reactions triggered by low glucose levels are trying to rebalance the glucose concentrations in our body to make it work properly.

In positive feedback, a product will only stimulate more the components that lead to that product to produce more of it, increasing the product's effect and an imbalance.
