feedback inhibition means that an increase in a substance will
A
decrease the production of that substance
B
increase production of that substance
C
increase the production of other substances
D
stop production of another substance
Explanation: 

Detailed explanation-1: -Feedback inhibition is an essential biochemical procedure that makes use of noncompetitive inhibitors to regulate some enzyme reactions. The final product in this process blocks the enzyme that catalyses the first reaction in a series. The synthesis of several amino acids is regulated by feedback inhibition.

Detailed explanation-2: -Feedback inhibition is the process by where the end product terminates the reaction. The accumulation of the end product interferes with the enzymatic activity by changing the shape of its active site.

Detailed explanation-3: -Complete answer: Allosteric inhibition is called feedback inhibition because in feedback inhibition, the end products of a reaction are known to bind to the allosteric site of the enzyme leading to the inactivation of enzyme thereby producing a lesser amount of products.

Detailed explanation-4: -Feedback inhibition involves the use of a reaction product to regulate its own further production (Figure 11). The cell responds to an abundance of the products by slowing down production during anabolic or catabolic reactions.
