Front

What is the primary function of the cell membrane?

Back

To protect the cell and regulate what enters and exits.

Front

What is active transport?

Back

The movement of molecules across a membrane using energy, usually against a concentration gradient.

Front

What is passive transport?

Back

The movement of molecules across a membrane without the use of energy, usually along a concentration gradient.

Front

What is the role of ATP in cellular processes?

Back

ATP provides energy for various cellular activities.

Front

What is the difference between hypertonic and hypotonic solutions?

Back

Hypertonic solutions have a higher concentration of solutes compared to the cell, while hypotonic solutions have a lower concentration.
