One Type of Biochemical Pathway Regulation Is Referred to as Feedback

One type of biochemical pathway regulation is referred to as feedback inhibition.This means that as the

A) cell produces more quantity of product through a biochemical pathway,the build up of that product will inhibit the activity of that product's production.
B) cell produces more quantity of product through a biochemical pathway,the activity will be increased or stimulated by the build up of that product.
C) cell produces less quantity of product through a biochemical pathway,the activity will be inhibited by not having enough of that product.
D) cell produces less quantity of product through a biochemical pathway,the activity of the substrate will be increased and that it will exceed capacity of the pathway.
