Membrane-Bound Organelles Have the Same Type of Membrane as the Plasma

Question

Membrane-bound organelles have the same type of membrane as the plasma membrane except
A) for the absence of a glycocalyx.
B) for the absence of cholesterol.
C) the nonpolar tails face outward.
D) they are all covered with ribosomes.

Accepted Answer

Membrane-bound organelles and the plasma membrane share similar structures, including lipid bilayers with embedded proteins. However, a key difference is the absence of a glycocalyx in membrane-bound organelles. The glycocalyx, a layer of carbohydrates attached to the membrane proteins and lipids, is primarily found on the cell's exterior surface, contributing to cell-cell recognition, communication, and adhesion.
