Low contentration

High concentration

Active transport

Passive transport

• Low contentration

• High concentration

• Active transport

• Passive transport

Match

Matching pairs -

• diffusion of water

• diffusion that uses a protein channel

• Gas molecules moving through phospholipid bilayer

• Passive transport is also called

osmosis

facilitated diffusion

simple diffusion

diffusion

• osmosis

• facilitated diffusion

• simple diffusion

• diffusion

Multiple Choice

When ions (atoms that are positively or negatively charged) move through the cell membrane, they use active transport. Why is this movement described as active transport?

• The ions are negative.

• The ions are attached to large proteins.

• The ions are trapped in the cell membrane.

• The ions are moving against the concentration gradient

Match

Match the following functions to each biomolecule in the cell membrane:

• cell recognition markers

• transport LARGE/charged molecules through the membrane

• allow small molecules to pass through the membrane

carbohydrates

proteins

phospholipids

• carbohydrates

• proteins

• phospholipids
