Passive transport _________ requires energy.

• never

• always

• sometimes

• only

Diffusion is:

• passive transport

• active transport

• both passive and active transport, depending on the situation

• neither passive or active transport

Osmosis is:

• Passive transport

• Active transport

• Both passive and active transport, depending on the situation

• Neither passive or active transport

In passive transport, molecules always move from a _____ concentration to a ____ concentration.

• low ---> high

• high ---> low

• (not this one)

• (not this one)

Diffusion and Osmosis are very similar, except that ________ involves the movement of water through a membrane.

• Osmosis

• Diffusion

• (not this one)

• (not this one)

Facilitated diffusion:

• Is passive transport and uses protiens

• Is active transport and uses proteins

• Is passive transport and uses ATP

• Is active transport and uses ATP

A large molecule, like sugar, requires what to move through the cell membrane?

• Facilitated diffusion and some help from a protein

• Active transport and some help from a protein
