Cell Transport Review

Front

What is the primary function of glycoproteins in the cell membrane?

Back

They play a key role in cell-cell recognition and communication.

Front

What is the hydrophobic region of the cell membrane?

Back

The hydrophobic region consists of the fatty acid tails of phospholipids, which repel water.

Front

What is the primary role of the phospholipid bilayer in the cell membrane?

Back

To act as a barrier, controlling what enters and exits the cell.

Front

How does exocytosis contribute to the functioning of a cell?

Back

By exporting waste materials out of the cell.

Front

Which of the following is NOT a component of the cell membrane?

Back

DNA.

Front

Define cell membrane.

Back

A biological membrane that separates and protects the interior of all cells from the outside environment.

Front

What are phospholipids?

Back

Molecules that make up the cell membrane, consisting of a hydrophilic head and two hydrophobic tails.

Front

Explain the term 'selective permeability.'

Back

The ability of the cell membrane to allow certain substances to pass while blocking others.

Front

What role do transport proteins play in the cell membrane?

Back

They facilitate the movement of substances across the membrane.

Front

What is the function of cholesterol in the cell membrane?

Back

To maintain fluidity and stability of the membrane.
