Question

Which of the following would not affect enzyme activity?

A) pH levels too high or too low
B) temperature that is too high
C) wear out from old age just like anything else
D) too much enzyme present for a chemical reaction

Answer 1

Factors such as pH levels, temperature, enzyme concentration, and substrate concentration can affect enzyme activity. Too much enzyme present for a chemical reaction would not have an impact on enzyme activity.

Step-by-step explanation:

The factors that can affect enzyme activity include pH levels, temperature, enzyme concentration, and substrate concentration.

A) pH levels too high or too low can affect enzyme activity. Extreme pH values can cause enzymes to denature and lose their function.

B) Temperatures that are too high can also denature enzymes, affecting their activity.

C) Enzymes do not wear out due to old age like other things. However, they can become less effective over time due to changes in their structure or the build-up of unwanted substances.

D) Too much enzyme present for a chemical reaction does not affect enzyme activity. Enzymes will only catalyze reactions when there is a sufficient amount of substrate present.
