Final answer:
Product Z is a feedback inhibitor of enzyme 1. In the presence of a high concentration of product Z, determine how feedback inhibition: c) Decreases enzyme activity
Step-by-step explanation:
In the presence of a high concentration of product Z, feedback inhibition decreases enzyme activity. Feedback inhibition is a regulatory mechanism in which the end product of a pathway inhibits an enzyme early in the pathway to control the rate of production. In this case, product Z acts as a noncompetitive inhibitor of enzyme 1, reducing its activity and slowing down the entire pathway.
This type of feedback control is important to prevent wasteful production of substrate A and conserve energy. It ensures that the pathway only proceeds when the final product is needed and avoids overproduction. This regulatory mechanism allows cells to maintain homeostasis and avoid toxicity.
Feedback inhibition decreases enzyme activity in the presence of a high concentration of product Z, preventing wasteful production and maintaining homeostasis. Therefore the correct answer is c) Decreases enzyme activity
