Cell Membrane & Transport

Front

What is an ISOTONIC solution?

Back

An isotonic solution has an equal concentration of solute compared to the inside of the cell.

Front

Which type of movement requires cellular energy?

Back

Active transport requires cellular energy.

Front

What is Passive Transport?

Back

Passive transport does NOT require cell energy.

Front

What happens to a cell in a 30% water 70% salt solution if the cell is 70% water?

Back

The cell will lose water and shrink.

Front

What is the difference between active and passive transport?

Back

Active transport uses ATP (energy) while passive transport does not require energy.

Front

Define Diffusion.

Back

Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is Osmosis?

Back

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

Front

What is a selectively permeable membrane?

Back

A selectively permeable membrane allows certain molecules to pass through while blocking others.

Front

What is the role of transport proteins in cells?

Back

Transport proteins help move substances across the cell membrane.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process of passive transport of molecules across a membrane via specific proteins.
