Question

question 4 (1 point)
which lipid type is a major component of cell membranes?
steroids
waxes
phospholipids
triglycerides

Explanation:

Cell membranes are composed of a phospholipid bilayer. Phospholipids have a hydrophilic (water - loving) head and hydrophobic (water - fearing) tails. This structure allows them to form a barrier that separates the inside and outside of the cell. Steroids like cholesterol are also in cell membranes but in smaller amounts. Waxes are more for protection (e.g., on plant leaves). Triglycerides are for energy storage.

Answer:

phospholipids
