Question

mini - quiz: ph and enzymes
score 100 %
based off of your observations, which of the following statements would be true?
i. substrates move faster at higher ph levels.
ii. there is an optimal ph level at which the enzyme works best. above or below the optimal ph, the enzyme becomes less effective.
iii. the enzyme denatures (loses its shape) at ph levels that are too high or too low.
a. i and iii only
b. ii and iii only
c. i only
d. i, ii, and iii

Explanation:

Enzymes have an optimal pH for maximum activity. Deviations from this optimal pH lead to decreased effectiveness and can cause denaturation. The movement speed of substrates is not directly related to pH in the way stated in I.

Answer:

B. II and III only
