Front

If there are 24 molecules inside a cell, how many would be inside and outside after diffusion?

Back

There would be 12 inside and 12 outside.

Front

What is Osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What is the main difference between Active and Passive Transport?

Back

Active transport requires energy, while passive transport does not.

Front

Define Concentration Gradient.

Back

The difference in concentration of a substance between two areas.

Front

What is a selectively permeable membrane?

Back

A membrane that allows certain molecules to pass while blocking others.

Front

What is the role of transport proteins in facilitated diffusion?

Back

They help move substances across the membrane without using energy.
