Cell Transport

Front

What is a selectively permeable membrane?

Back

A selectively permeable membrane allows certain size substances to enter and leave.

Front

What process helps maintain a normal internal cellular environment in the human body?

Back

Osmosis is the process that helps maintain a normal internal cellular environment.

Front

What is passive transport?

Back

Passive transport is when substances move in and out of cells using only their own kinetic energy.

Front

What happens to a red blood cell in a hypotonic solution?

Back

A red blood cell will swell and burst in a hypotonic solution.

Front

What is equilibrium in the context of molecular movement?

Back

Equilibrium refers to molecular movement that continues even when there is no overall change in concentration.

Front

Define diffusion.

Back

Diffusion is the process by which molecules spread from areas of high concentration to areas of low concentration.

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane.

Front

What is active transport?

Back

Active transport is the movement of substances against their concentration gradient, requiring energy.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy, while active transport does.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of a cell.
