Respuesta :

Answer:

reduced

Explanation:

Nicotinamide adenine dinucleotide is the cofactor which is found in all living cells. It exists in two forms:  

  • Oxidized form which is abbreviated as NAD⁺
  • Reduced form which is abbreviated as NADH.

NAD is involved in the redox reactions in metabolism, carrying the electrons from one reaction to the another. NAD⁺ is oxidizing agent which means that it accepts the electrons from the other molecules and becomes reduced. The reaction forms NADH.
