Consider a biochemical pathway with five steps that lead to the production of product Q.If there is an abundance of product Q,the most efficient way to slow down the entire pathway would be to regulate _____________________.

Question

Quizplus · Accepted Answer

Regulating the first enzyme in a biochemical pathway is the most efficient way to control the entire pathway because it acts as a gatekeeper. If the activity of the first enzyme is reduced, the flow of substrates through the entire pathway is decreased, effectively slowing down the production of the end product, in this case, product Q. This is an example of feedback inhibition, where the abundance of the end product inhibits the activity of the first enzyme, conserving resources and energy by not overproducing the product.
