The Organic Molecule in Cell Membranes That Forms Channels Is

Question

The organic molecule in cell membranes that forms channels is:
A)protein
B)cholesterol
C)phospholipids
D)oligosaccharides

Accepted Answer

The organic molecule that forms channels in cell membranes is typically a protein. Proteins can fold into specific shapes and form channels that allow for the selective transport of molecules across the cell membrane. Cholesterol is a type of lipid that can affect the fluidity of the membrane, but it does not form channels. Phospholipids are the main structural component of the membrane, but they do not form channels on their own. Oligosaccharides are carbohydrates that are often attached to proteins or lipids on the outer surface of the membrane, but they also do not form channels.
