Cell Membrane/ Transport

Front

What is the function of the plasma membrane?

Back

To regulate what enters and leaves the cell.

Front

What is the hydrophobic region of the cell membrane?

Back

The hydrophobic region is primarily composed of the fatty acid tails of phospholipids.

Front

What are the main components of the cell membrane?

Back

Most of the cell membrane is made of lipids.

Front

What forms the channels and pumps in the phospholipid bilayer?

Back

Proteins form the channels and pumps in the phospholipid bilayer.

Front

What is a phospholipid?

Back

A phospholipid is composed of a phosphate and glycerol head and 2 fatty acid chain tails.

Front

What is the role of proteins in the cell membrane?

Back

Proteins assist in transport, act as receptors, and provide structural support.

Front

What is the structure of the cell membrane?

Back

The cell membrane is a phospholipid bilayer with embedded proteins.

Front

What does 'selectively permeable' mean in relation to the cell membrane?

Back

It means the membrane allows certain substances to pass while blocking others.

Front

What is the significance of cholesterol in the cell membrane?

Back

Cholesterol helps to stabilize the membrane's fluidity.

Front

What are glycoproteins and their function?

Back

Glycoproteins are proteins with carbohydrate chains that play a role in cell recognition.
