Question

The layer of carbohydrates on the external surface of a cell is called what?

A) inclusion
B) glycocalyx
C) glycogen
D) glycolipid
E) desmosome

Answer 1

The layer of carbohydrates on the external surface of a cell is called the glycocalyx. It consists of carbohydrate chains bound to proteins or lipids and plays important roles in cell recognition and cell-to-cell attachments. Hence the correct answer is option B

Step-by-step explanation:

The layer of carbohydrates on the external surface of a cell is called the glycocalyx. The glycocalyx consists of carbohydrate chains that are bound either to proteins (forming glycoproteins) or to lipids (forming glycolipids). The glycocalyx plays important roles in cell recognition, self/non-self determination, embryonic development, and cell-to-cell attachments.

Hence the correct answer is option B
