<h2>The correct answer is:  Statement 3, (have a great deal.........protein (antibody).</h2>

Explanation:

  • Plasma cells are also known as Plasma B cells.
  • They are one of the types of white blood cells which develop inside the bone marrow.
  • Inside the bone marrow are present the multipotent hematopoetic stem cells.
  • These cells differentiate to form the myeloid stem cells and the lymphoid stem cells.
  • The lymphoid stem cells develop into the lymphoblasts which further differentiate to form the B lymphocytes, T lymphocytes and Natural Killer cells respectively.
  • The B lymphocytes form the plasma cells.
  • These plasma cells produce antibodies which target foreign materials or organisms and tag them to be recognized and destroyed by other cells of the immune system like macrophages, T cells, Natural Killer cells, etc.
  • The antibodies are composed of proteins.
  • Hence, in order to produce huge amounts of antibodies (proteins) the B cells have huge quantity of rough endoplasmic reticulum (RER).
  • This is because secretory proteins or proteins present in the plasma membrane are synthesized by the ribosomes attached to the endoplasmic reticulum (ER), that is, the RER.

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.
