Active vs Passive Transport

Most of the cell membrane is made of...

• Lipids

• Carbohydrates

• Proteins

• Nucleic acids

The function of the cell membrane is....

• to regulate what enters and leaves the cell.

• fight bacteria and viruses that enter the cell.

• provide rigid support and protection to the cell.

• make sure each cell can move

• Passive Transport

• Active Transport

What is equillibrium?

• When concentrations cannot be balanced between two substances 
• When concentrations are balanced between two substances 
• Making the energy in the top half of your body equal the the energy in the bottom half
