Question

You will be putting a drop of hydrogen peroxide on the edge of your plate as one of many tests used to identify bacteria. If it bubbles, this means that: a. it is a negative reaction, meaning that catalase is present b. it is a positive reaction, meaning that catalase is present c. it is a negative reaction, meaning that catalase is not present d. it is a positive reaction, meaning that catalase is not present

Answer 2

On putting a drop of hydrogen peroxide on the edge of your plate as one of many tests used to identify bacteria. If it bubbles, this means that

b. It is a positive reaction.

Hydrogen peroxide Test:

Hydrogen peroxide decomposes into water and oxygen upon heating or in the presence of numerous substances. This test is used to identify organisms that produce the enzyme, catalase.

This enzyme detoxifies hydrogen peroxide by breaking it down into water and oxygen gas. The bubbles resulting from production of oxygen gas clearly indicate a catalase positive result.

Thus, the correct option is b.
