Question

Quizplus · Accepted Answer

The main components in biological membranes are lipids, proteins, and carbohydrates. Lipids make up the majority of the membrane structure and include phospholipids, cholesterol, and glycolipids. Proteins are embedded within the lipid bilayer and have various functions such as transport, signaling, and enzyme activity. Carbohydrates are also present on the outer surface of the membrane and play a role in cell recognition and communication. Nucleotides, nucleosides, monosaccharides, and polysaccharides may be present in the membrane but are not the main components. Enzymes, electron acceptors, and electron donors may be present in the membrane but are not components of the membrane structure. Cholesterol and polar water molecules are part of the membrane but not the main components.
