Back

cell membrane

Front

Which is true about active transport?

Back

It requires energy.

Front

The movement of molecules from an area of higher concentration to an area of lower concentration is called ____________.

Back

diffusion

Front

The diagram is an example of _____________.

Back

diffusion

Front

This is a diagram of ______________.

Back

osmosis

Front

What is osmosis?

Back

The movement of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is the difference between active transport and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not require energy and moves substances down their concentration gradient.

Front

Define diffusion.

Back

The process by which molecules spread from areas of high concentration to areas of low concentration.

Front

What is equilibrium in the context of cell transport?

Back

A state where the concentration of a substance is equal throughout a space.

Front

What role does the cell membrane play in transport?

Back

The cell membrane regulates what enters and exits the cell, maintaining homeostasis.
