Which of the following oxidizing agents is necessary to complete the biochemical reaction below?

aldehyde dehydrogenase
CH3COH + ______ → CH3COOH

a. K2Cr2O7
b. NAD+
c. Cu2+
d. NADH


Sagot :

Answer:

b. NAD+

Explanation:

Aldehydes are oxidized to carboxylic acids in the presence of strong oxidizing agents.

In a biochemical system, the same oxidation reaction occurs by the help of the enzyme alcohol dehydrogenase and NAD+ which is a biological oxidizing agent.

NAD+ is an effective biological oxidizing agent that accepts electrons from molecules and change to its reduced form NADH, which is an effective biological reducing agent that donates electrons. Electron transfer processes are the main functions of NAD+.
