Which of the following changes gives a saturation curve for the rate of enzyme activity?
A) an increase in enzyme concentration
B) an increase in substrate concentration
C) an increase in temperature
D) an increase in pH

Question

Quizplus · Accepted Answer

Saturation occurs when all enzyme active sites are occupied by substrate molecules. Therefore, increasing substrate concentration will eventually reach a point of saturation and result in a saturation curve for enzyme activity. Increasing enzyme concentration, temperature, and pH can increase the rate of enzyme activity, but they do not necessarily result in a saturation curve.
