Cell Membrane & Transport Final

What means of particle transport requires energy?

• passive
• active
• facilitated

What is the diffusion of water through a selectively permeable membrane?

• active transport
• osmotic pressure
• facilitated diffusion
• osmosis

Diffusion is the movement of particles

• from low to high concentration
• from  high to low concentration
• from equilibrium to areas of high concentration
• all of the above

What characteristic of the cell membrane allows only certain material to pass through?

• selective gating
• selective permeability
• hydrophilia
• selective service

Facilitated diffusion requires

• no energy
• energy

Placing a cell in an isotonic solution causes the cell to

• shrink
• swell
• stay the same

Active transport is the movement of large materials across a cell membrane from ______ to ______ concentration

• high to low

• low to high

• high to high

• low to low

Active transport across a cell membrane from low to high concentration, requires

• energy (ATP)

• no energy

• water

• oxygen

A general term for the various types of active transport that move particles into a cell by enclosing them in a vesicle made out of plasma membrane.

• Endocytosis

• Exocytosis

• Osmosis

• Diffusion

A form of bulk transport in which materials are transported from the inside to the outside of the cell in membrane-bound vesicles that fuse with the plasma membrane.
