What is the major role of NAD+?

a. NAD+ acts as an electron transporter
b. NAD+ catalyzes the addition of a phosphate to the glucose molecule as it enters the cell.
c. NAD+ catalyzes the addition of a phosphate to ADP to form ATP
d. NAD+ catalyzes the addition of an electron to ADP to form ATP

The correct Answer is A) NAD+ acts as an electron transporter.

Explanation:

Nicotinamide Adenine Dinucleotide (NAD+) is an oxidizing agent – it accepts electrons from other molecules and becomes reduced. It function is more like that of a courier, carrying electrons to the cells that need it to produce and store energy.

This reaction forms NADH, which can then be used as a reducing agent to donate electrons. These electron transfer reactions are the main function of NAD.

Option A is the correct answer –NAD+ acts as an electron transporter.

Explanation:

NAD + (Nicotinamide Adenine Dinucleotide) is an organic coenzyme like would see below it is involved mostly in biological oxidation and reduction reactions.

Enzymes that use NAD + /NADH uses it for the following functions;

• Catalyzes important step in glycolysis

• Metabolizes alcohol

• Catalyzes reactions connecting glycolysis to the Krebs cycle

• Catalyzes reactions in muscle and liver cells

• Important in fat catabolism

• Catalyzes reactions in the Krebs cycle, aerobic metabolism

• Catalyzes oxidative phosphorylation reactions.

It should be noted that NAD+ is functions as the electron transporter in the liver

the  frequency of a wave represents  the number of wavelengths that pass a specific point per second. the unit for  frequency  is hertz (hz).

some fungi obtain their nutrients from a living host (plant or animal) and are called most biotrophic fungi have fairly narrow host ranges—they are specialized on a limited called rhizomorphs that allow the fungus to grow from one tree to another. ascospores are formed inside a sac-like structure called an ascus. so your answer is a
