Question

Quizplus · Accepted Answer

Marker molecules on the outer surface of the plasma membrane are typically carbohydrate chains, also known as glycoproteins or glycolipids. These carbohydrate chains are involved in cell-cell recognition and help to identify the cell type. ATP, amino acids, nucleotides, and inorganic ions are not typically found on the outer surface of the plasma membrane as marker molecules.
