Glucocalyx is

Options

A. Glycoproteins and glycolipids
B. Oligosaccharide part of glycolipids and glycoproteins
C. Lipid and protein parts of glycolipids and glycoproteins
D. Mucopolysaccharides attached to cell wall

Answer

**Step-by-Step Solution:**

1. **Definition of Glycocalyx**: Glycocalyx is a pericellular matrix that is primarily found on the outer surface of the cell membrane in various types of cells, including bacterial cells.

2. **Location**: In bacterial cells, glycocalyx is located on the cell membrane, not the cell wall. It plays a crucial role in the structure and function of the cell.

3. **Functions of Glycocalyx**:
- **Cell-Cell Interaction**: Glycocalyx is involved in facilitating interactions between cells, which is essential for tissue formation and communication.
- **Cell Recognition**: It aids in the recognition of cells by other cells, which is important for immune responses and cellular signaling.

4. **Composition**: Glycocalyx is primarily composed of carbohydrate chains. These carbohydrate chains are attached to proteins and lipids, forming glycoproteins and glycolipids, respectively.

5. **Positioning**: The carbohydrate components of glycocalyx are oriented towards the outer surface of the plasma membrane, making them accessible for interactions with the external environment.
