Question

An ATPase enzyme breaks down ATP into ADP and phosphate using water in the reaction. This enzyme is in the enzyme class

Answer 1

Answer: The correct answer is-

Hydrolase.

Hydrolase is a class of enzyme that includes biochemical catalysts, which ulitize water to break down any chemical bond (a process called hydrolysis).

In other words, any enzyme that hydrolyzes a substrate belongs to Hydrolase class of enzymes.

In this question, enzyme ATPase catalyses hydrolysis of ATP in order to form ADP and inorganic phosphate to (with the help of water) along with the release of large amount of energy.

Thus, it belongs to Hydrolase class of enzyme.

Answer 2

Hydrolase

This is because it catalyzes a hydrolysis reaction.
