Active & Passive Transport

The difference in the concentration of a substance from one location to another is called 

• diffusion
• osmosis
• concentration gradient
• passive transport

A molecule that diffuses down a concentration gradient goes from an area of ______ concentration into an area of ______ concentration.

• high, low
• low, high
• passive, active
• active, passive

Passive transport requires no

• concentration gradients
• osmosis
• motion
• energy

Controlling what goes into or out of the cell without energy is called

• active transport
• endocytosis
• passive transport
• exocytosis

Controlling what goes into or out of the cell with the help of energy is called

• active transport
• endocytosis
• passive transport
• exocytosis

The movement of molecules against a concentration gradient

• simple diffusion
• facilitated diffusion
• active transport
• osmosis

Movement of particles through the cell membrane from high to low

• passive transport
• active transport
• facilitated diffusion
• osmosis 

Most active transport proteins use energy from the breakdown of:

• nucleus
• cell membrane
• ATP
• mitochondria

Against the concentration gradient
low to high
uses energy/ATP

• facilitated diffusion
• osmosis
• active transport

Particles move from high to low.
Doesn't need energy
