Does Reduction Release Energy?

Answer: Reduction occurs when a molecule gains an electron or decreases its oxidation state. When a molecule is reduced, it gains energy.

Is reduction Endergonic or Exergonic?

Exergonic reactions can be coupled to endergonic reactions. Oxidation-reduction (redox) reactions are examples of the coupling of exergonic and endergonic reactions. Enzymes often act by coupling an endergonic reaction to the exergonic hydrolysis of ATP.

What does it mean if a molecule is reduced?

Reduction is the loss of oxygen atom from a molecule or the gaining of one or more electrons. A reduction reaction is seen from the point of view of the molecule being reduced, as when one molecule gets reduced another gets oxidised. The full reaction is known as a Redox reaction.
