Correct Answer : B,D,E
A. For fluid balance: Lipids do not play a direct role in maintaining fluid balance; electrolytes and plasma proteins like albumin regulate this function.
B. As a component of the myelin sheath: Lipids, particularly phospholipids and cholesterol, are essential for forming the myelin sheath, which insulates nerve fibers and facilitates efficient nerve conduction.
C. Component of hemoglobin: Hemoglobin is composed of iron and protein (globin chains), not lipids.
D. As a component of the cell membrane: Cell membranes are composed of a lipid bilayer (phospholipids and cholesterol), which helps maintain structural integrity and fluidity.
