Question

Identify the type of feedback mechanism that results in the rate of a process increasing as the concentration of the product increases.

A) neutral feedback


B) positive feedback


C) negative feedback


D) oscillating feedback

Answer 1

This is a positive feedback reaction. If both ends of the reaction are increasing, that means that it is a positive feedback reaction. 

Answer 2

The correct answer is option B

In a positive feedback the presence of a chemical or product intensifies or increases the resulting action/product. For example , during child birth the release of oxytocin intensifies the process of contraction. Another example is of blood platelets which when increase in number also enhances the rate of the blood clothing. While in a negative feedback the presence of a chemical or product reduces or discourages the resulting action/product.
