Cellular Transport Review

Front

What happens to a cell with 80% water when placed in a solution with 50% solute and 50% water?

Back

The cell will shrink.

Front

What does it mean to be hydrophilic?

Back

It means water loving.

Front

What is the movement of small molecules (like carbon dioxide or oxygen) across the cell membrane from high concentration to low concentration called?

Back

Diffusion.

Front

Which part of a phospholipid is hydrophobic?

Back

The tail.

Front

What is a solution with a higher concentration of solutes compared to the cell called?

Back

Hypertonic solution.

Front

What is osmosis?

Back

The movement of water across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is a hypotonic solution?

Back

A solution with a lower concentration of solutes compared to the cell.

Front

What is isotonic solution?

Back

A solution with the same concentration of solutes as the cell.

Front

What is facilitated diffusion?

Back

The process of passive transport of molecules across a cell membrane via specific transmembrane integral proteins.

Front

What role do transport proteins play in cellular transport?

Back

They help move substances across the cell membrane that cannot directly diffuse through the lipid bilayer.
