transport answers

1. Osmosis, diffusion, and facilitated transport
2. Proteins
3. Membrane Proteins
4. Glucose is moving from a higher to a lower concentration
5. Lipid Bi-layer
6. Diffusion of water across a membrane 
7. If it does not pump out all of its extra ions to be even the water is going to move in and it can swell and explode.
8. Energy!!!!!!! 
9. Proteins
10. No , they are very specific.
11. Pumping ions from lower to higher concentration
12. Nerve cells
13. Inhibitors
14. Phagocytosis: cell eats
Pinocytosis: cell drinks
15.the whole cell works during endocytosis. Just a few proteins work during active transport
16. If the cells weren’t small, itd be harder to balance.
17. Proteins: Are the doors for the active transport and facilitated diffusion
Lipids: Make the cell membrane.
Carbs. Provide the energy for active transport
