Question

If ATP is hydrolyzed in a test tube, which of the following effects indicates that the reaction is exergonic?

A) Release of energy drops the temperature in the test tube.

B) Release of energy has no effect on the surroundings.

C) Release of energy heats the surrounding water in the test tube.

Answer 1

Answer:

The correct answer is option C.

Explanation:

Exergonic reaction are those reaction which releases energy into the surroundings.

Endergonic reaction are those reaction which absorbs energy from the surroundings.

When ATP is hydrolyzed to give energy and ADP.Thus means that energy is released during the reaction into the surrounding.

So, when the hydrolysis of ATP is carried out in test tube it gives out energy which rises the temperature of the water in the test tube.

Hence, Exergonic reaction.
