• B. Lipids
• C. Glycolipids
• D. Glycoproteins

Answer 1

Answer:

B. Lipids

• Lipids are the largest constituent of the membrane of the erythrocyte in human beings and are also responsible for performing most of the functions of the membrane.

• Lipids are composed of triglycerides, cholesterol, phospholipids, and sphingomyelin which form a bilayer that is semi-permeable and acts as a barrier to separate intracellular components from extracellular components.

• The proteins act mainly as receptors for other molecules, enzymes, or hormones, while lipids aid in controlling diffusion rates and maintaining structural integrity.
