Front

What is the function of proteins in the cell membrane?

Back

Proteins facilitate transport, act as receptors, and provide structural support.

Front

What is the role of carbohydrates in the cell membrane?

Back

Carbohydrates are involved in cell recognition and signaling.

Front

What is the structure of a phospholipid?

Back

A phospholipid consists of a hydrophilic head and two hydrophobic tails.

Front

What is the fluid mosaic model?

Back

The fluid mosaic model describes the cell membrane as a flexible layer made of lipid molecules with embedded proteins.

Front

What is the significance of the selective permeability of the cell membrane?

Back

Selective permeability allows the cell to maintain homeostasis by controlling what enters and exits.
