Cell Structure / Cellular Transport

Front

What is an element?

Back

An element is any substance that cannot be broken down into simpler substances.

Front

What energy source do active transport proteins use?

Back

Active transport proteins use energy from the breakdown of ATP.

Front

What are two examples of passive transport?

Back

Diffusion and Osmosis.

Front

What happens to a cell in a hypotonic solution?

Back

A cell will swell and perhaps burst (lyse) in a hypotonic solution.

Front

What does permeable mean?

Back

Permeable means that things can pass through.

Front

What is a compound?

Back

A compound is a substance formed when two or more elements are chemically bonded together.

Front

What is the function of the cell membrane?

Back

The cell membrane controls what enters and exits the cell, providing protection and support.

Front

What is osmosis?

Back

Osmosis is 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 diffusion?

Back

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

Front

What is active transport?

Back

Active transport is the movement of substances across a cell membrane against their concentration gradient, requiring energy.
