If energy is needed to move

materials into or out of a cell,

what is most likely occurring?

• active transport

• passive transport

• osmosis

• diffusion

In diffusion, substances move from ______ to _____ concentrations.

• high to low
• low to high

Which does NOT require energy to occur?

• Passive Transport
• Active Transport
• Endocytosis
• Exocytosis

What is the difference between active and passive transport?

• Active does not need energy and passive uses ATP (energy)
• Active uses ATP (energy) and passive does not need energy
• Active stores transport proteins and passive releases 
• Active uses hormones and passive does not 

Why does ACTIVE TRANSPORT require energy?

• It's moving molecules against their concentration gradients

• It's moving molecules with their concentration gradient

• It doesn't

The movement of atoms, ions, or molecules from an area of high concentration to an area of low concentration.

• osmosis
• active transport
• diffusion
• hypertonic
