Chapter 8 Review

What is it called when large molecules move across the cell membrane from an area of high concentration to an area of low concentration through a protein channel?

• Diffusion

• Osmosis

• Active Transport

• Facilitated Diffusion

The movement of particles from an area of high to low concentration is known as--

• Passive Transport

• Active Transport

Cell membrane transport that occurs without energy is called--

• active transport

• endocytosis

• passive transport

• 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 

The movement of molecules from low to high is known as

• simple diffusion
