Which of the following will most likely happen to an enzyme if it is placed in

an environment that is too acidic or too basic?

The enzyme will no longer bind to the substrate, slowing or stopping the chemical reaction

Explanation:

The enzyme will get denatured and therefore its active site (that binds the substrate) will be deformed and unable to catalyze reactions. The enzymes, mostly made of folded proteins, are made stable by the interactions between the protein's amino acids side groups. Changes in the pH of the solution influence the charges of these groups hence altering their interactions. This causes the protein enzyme to deform causing it to lose its function.
