Question

In a lab experiment with peroxide and yeast, the hydrogen peroxide (2H2O2 ) breaks down into water (2H2O liquid) and oxygen (O2 gas) in the presence of yeast. The yeast serves as a ________.

Catalyst in the decomposition of the hydrogen peroxide

Substrate in the decomposition of the hydrogen peroxide


Active site between the hydrogen peroxide and water

Synthesis in the decomposition of hydrogen peroxide

Answer 1

Answer:Substrate in the decomposition of the hydrogen peroxide

Explanation:

Answer 2

The yeast serves as a catalyst in the decomposition of the hydrogen peroxide.

CATALYST:

• A catalyst is a substance that increases the rate of a chemical reaction without getting used up in the process.

• A catalyst increases the rate at which a reaction occurs by lowering the activation energy of the reaction.

• According to this question, hydrogen peroxide (2H2O2) breaks down into water (2H2O) and oxygen gas (O2) in the presence of yeast.

• The yeast in this question serves as a catalyst that increases the rate at which the decomposition of hydrogen peroxide occurs.

• Therefore, the yeast serves as a catalyst in the decomposition of the hydrogen peroxide.
