Text Solution

Verified by Experts

(a) Protein synthesis: RBCs do not have ribosomes which are important for protein synthesis. They are concerned with transport of respiratory gases alone. Hence protein synthesis could not take place in RBCs.
(b) Cells division: RBCs do not have numbers. They are produced in the bone marrow. They do not involve in cell division.
(c) Lipid Synthesis: Lipid synthesis occurs in endoplasmic reticulum (ER) and golgi complex. The ER is absent in RBCs. Hence lipid synthesis does not take place in RBCs.
(d) Active transport: Transport of respiratory gases between the alveoli to the blood vessels, blood vessel to the cells and vice versa take place due to difference in the partial pressure of O, and CO,. Active transport of materials against concentration gradient does not take place in RBCs.
