Answer:
<em>It acts as a catalyst, lowing the activation energy and speeding up a reaction.</em>
Explanation:
The acetaldehyde alcohol dehydrogenase is used to turn acetaldehyde to ethanol.
In the end it releases 2ATP. Yet it has not given energy in the reaction under any conditions to carry it to fruition.
This merely decreases the reaction's activation energy and favors its operation within physiological circumstances.
