Which type of transport requires an input of energy?

• Passive Transport
• Osmosis
• Simple Diffusion
• Active Transport

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

Which BEST describes ACTIVE TRANSPORT?

• Moves substances from a dilute solution to a concentrated solution (against a concentration gradient). This requires energy from respiration.

• Moves substances from a concentrated solution to a dilute solution (with a concentration gradient). This does not require energy from respiration.
