The NADPH generated by the pentose phosphate pathway primarily serves as a
Igoryamba

Answer:

Option-A

Explanation:

Pentose phosphate pathway is the alternative pathway taking place in both eukaryotes and prokaryotes parallel to the glycolysis.

The pentose phosphate pathway forms the electron carriers called NADPH and the ribose-5 phosphate.

The NADPH is formed in large amounts through this pathway which contains a very high amount of energy. NADPH can donate its hydride ions, therefore, it can be involved in the reaction where it can donate energy in the form of hydrogen and electron.

The NADPH is therefore involved in the formation of reducing biosynthetic pathways like fatty acid synthesis, cholesterol synthesis, and bile acid synthesis.

Thus, Option-A is the correct answer.
