If we add more substrate to an already occurring enzymatic reaction and it has no effect on the rate of reaction, the process is called _.
Correct answer: D. Saturation
- A. Denaturation
- B. Composition
- C. Inhibition
- D. Saturation
Explanation
Saturation refers to the point in an enzymatic reaction where all of the enzyme's active sites are occupied by substrate molecules, resulting in a maximum rate of reaction that cannot be increased by adding more substrate.

About Factors Affecting Enzyme Action
Enzyme activity changes with temperature, pH, substrate concentration and enzyme concentration because these factors affect molecular collisions and the active site. Questions also examine optimum conditions, denaturation and inhibition, while distinguishing a fall in activity caused by unsuitable conditions from permanent enzyme damage.
