Based on the image, what is the composition of monolayer I and the functions of its individual elements?

Based on the provided image and OCR, here's a description of the composition of monolayer I and the functions of its elements:

• 1a, 1б, 1в, 1г: These likely represent different types of proteins or lipids within the monolayer. Without further context, it's difficult to specify their exact function, but proteins (1б и 1в) often serve as receptors, channels, or enzymes, facilitating transport or signaling across the membrane. Lipids (1a, 1г) contribute to the structural integrity and fluidity of the membrane.
• 4: This points to the glycocalyx, which consists of carbohydrate chains attached to lipids and proteins on the outer surface of the cell membrane. It plays a role in cell recognition, cell adhesion, and protection from mechanical and chemical damage.

• I: Monolayer I is the external surface of the cell membrane.
