Carbohydrates are present in the plasmalemma in the form of

AHemicellulose
BCellulose
CStarch
DGlycoprotein
Correct Answer

Solution

Major components of plasma membrane are proteins and lipids. Carbohydrates occur in bound form in plasma membrane. Carbohydrates of cell membranes are small unbranched or branched chains called oligosaccharides. They are attached to both lipids and proteins molecules found on the surface of membranes as glycolipids and glycoproteins respectively.
So, the correct answer is 'Glycoprotein'
