How did varying the amount of enzyme effect the reaction?

Question 2 options:

A. It decreased the rate of the reaction

B. It had no effect on the rate of the reaction

C. The reaction was so vigorous the test tube broke

D. It increased the rate of the reaction

It's to increase the rate of the reaction.

D. It increased the rate of the reaction

Explanation:

Enzymes are proteins that catalyze chemical reactions in living things. Enzymes are catalysts, that is, substances that, without being consumed in a reaction, significantly increase their speed. They do not make impossible reactions feasible, but only accelerate those that could spontaneously occur. This makes it possible for physiological conditions to take place that without catalyst would require extreme conditions of pressure, temperature or pH.

Almost all chemical reactions that take place in living things are catalyzed by enzymes. Enzymes are specific catalysts: each enzyme catalyzes a single type of reaction, and almost always acts on a single substrate or on a very small group of them.
