Back

Cell Membrane

Front

What is diffusion?

Back

The movement of particles from high conc. to low conc. in a given space

Front

Which type of passive transport uses proteins to help molecules pass through the membrane?

Back

Facilitated diffusion

Front

What does it mean when cell membranes are described as selectively permeable?

Back

Cell membranes regulate which substances can enter and exit the cell.

Front

Which part of the cell controls the movement of substances?

Back

cell membrane

Front

Functions of a cell membrane EXCEPT:

• surrounding and protecting the contents of the cell
• releasing waste products from the cell
• producing energy for the cell processes
• allowing gases to enter the cell

Back

producing energy for the cell processes

Front

Which characteristic of a cell membrane allows it to control materials entering and leaving a cell?

Back

A cell membrane is semi-permeable.

Front

Passive Transport

Back

Does NOT require cell energy

Front

What is diffusion?

Back

when molecules move from a high concentration to a low concentration.

Front

When both inside and outside of a cell have the same amount of water, the cell has reached a state of: Osmosis, Diffusion, Equilibrium

Back

Equilibrium
