HAPPY WEDNESDAY 1. Turn in Page 37 (Osmosis Practice Problems) – Write “CORRECTED” on it BIG and CIRCLED if you did
corrections. Everyone TURN IT IN!!!2. On your Bellwork Sheet write “Finish Molecule Transport Foldable (Page 35)”
= water molecule
= oxygen molecule
= ATP/energy
= movement
• Diffusion OR Osmosis OR Facilitated Diffusion OR Active Transport
• Does it use energy?• What’s moving? Water OR Solutes• Is it moving from High to Low OR Low
to High? • Does it move through the
Phospholipid Bilayer OR Protein Channel?
