The new gene scientists added to Caldicellulosiruptor bescii that is transcribed and translated to produce an enzyme named bifunctional acetaldehyde and alcohol dehydrogenase. What role does this enzyme play in the production of ethanol? It acts as a catalyst, releasing energy that makes an unfavorable reaction become favorable. It acts as an energy source in a coupled reaction, releasing energy that makes that makes an unfavorable reaction become favorable. It acts as a catalyst, lowing the activation energy and speeding up a reaction. It acts as an energy source in a coupled reaction, lowing the activation energy and speeding up a reaction.

It acts as a catalyst, lowing the activation energy and speeding up a reaction.

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.

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.

explanation:

your answer would be a, maximum exploitation of resources.
