Cell Membrane and Transport Flashcard

Front

Which best describes a semi-permeable membrane?

Back

Allows certain molecules to pass while restricting others

Front

The phospholipid bilayer of the cell membrane has:

Back

Hydrophilic heads facing water and hydrophobic tails facing inward

Front

Which process requires no energy (ATP)?

Back

Facilitated diffusion

Which process moves molecules from low concentration to high concentration?

Back

Active transport

Front

Osmosis is specifically the movement of:

Back

Water across a selectively permeable membrane

Front

A red blood cell placed in a hypertonic solution will:

Back

Shrink due to water loss

Front

A cell placed in a hypotonic solution will:

Back

Swell as water enters

Front

A solution is isotonic to a cell when:

Back

Water moves in and out at equal rates

Front

Which membrane transport method uses transport proteins but no energy?
