All of the following may inhibit enzymatic reactions EXCEPT

Explanation

Environmental conditions such as heat or acidity inhibit enzymatic reactions by changing the shape of the active site and rendering the enzyme ineffective. Certain chemicals inhibit enzymatic reactions by changing the shape of the enzyme’s active site. If there is a lack of substrate, the enzyme will have no substance to affect. Thus, all of these factors may inhibit enzymatic reactions except an excess of substrate, which would not inhibit those reactions.
