Cell Membrane and Homeostasis

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

• Passive Transport

• Active Transport

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

How does a cell maintain homeostasis?

• By controlling what enters and leaves the cell

• Flexibility

• Protective barrier

• Structure and support

What is homeostasis?

• How the body releases oxygen

• Passive transportation

• Balance in the body

• 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 

ALL living cells have this in common

• Nucleus
• Cell Membrane
• Cell Wall
• Mitochondria
