Homework Statement
(Last one!) I think I filled out this table correctly, I just want someone to check over it for me, if you would :)
Oxygen enters cells by simple diffusion, glucose enters most cells by carrier assisted (facilitated) diffusion, the sodium/potassium pump removes sodium from cells and, when it enters at all sodium enters through ion channels.
Fill out the following chart:

Homework Equations
Information you need to understand-
Passive Transport: moves "down" gradient from high concentration to low concentration. energy comes from gradient; not the cell. 2 types
1. Simple Diffusion:: can diffuse directly through plasma membrane, small in size/ hydrophobic
2. Facilitated Diffusion:: there are proteins that help diffuse.
Active Transport: moves "up" gradient from low concentration to high concentration. Uses energy from the cell (ATP) to move against the gradient.
Sodium-Potassium Pump:: Sodium concentration higher on outside, Potassium concentration higher on inside. 3 Sodium out for every 2 Potassium in. Active transport.
