Types of Active transport

-ion pumps

-Co transport

-Endocytosis.

Active Transport

Relatively Negative Ion

ATP Outcome:ADP + Pi

Relatively positive ions

This is a process in which molecules are moves across the cell membrane. It is based on the atomic substances permeability or how a item responds to it magnetic field.

In order for your small intestine to send thing to your blood stream it most go through diffusion. Once it in your bloodstream it most use passive transport to get into the blood cell. This help your body function.

What is Diffusion?

Diffusion is when a molecule moves from a high concentration to a low concentration.
