Question

In the human stomach, chemical reactions take place in an acidic environment. Some of these reactions are catalyzed by enzymes. How would these enzymes most likely function in an environment where the pH was doubled?

(A)The enzymes would interfere with chemical reactions by bonding with the reactants.
(B)The enzymes would not be able to function properly outside of their optimal pH range.
(C)The rate of the reactions that are catalyzed by the enzymes would double.
(D)The rate of the reactions would increase as the PH is increased. ...?

Answer 1

The correct answer to this question is (B) The enzymes would not be able to function properly outside of their optimal pH range. This is how these enzymes would most likely function in an environment where the pH was doubled. Thank you for posting your question. I hope that this answer helped you.

Answer 2

The chemical reactions catalyzed by the enzymes in acidic environment will be affected if the pH is increased. The enzymes will not be able to function properly if the pH is doubled, and hence, the rate of the reactions will be decreased. The enzymes function at a optimum pH, and their activity decreases if this optimal pH is disturbed. The enzymes working in an acidic environment, thus, will not be able to function as before as the pH rises above their optimal temperature. The active sites of the enzymes gets damaged at a pH above or below the optimal temperature.

Hence, the answer is 'Option B - The enzymes would not be able to function properly outside of their optimal pH range'.
