**Welcome back!**
- Cells test, reassessment: grades posted, will hand back when everyone has taken it - hand back and go over exams - discuss types of proteins in membranes
 * hormone binding

HW; //Tiger// book 28-33, DBQ pg. 31

Cool electron microscope images.
 * 1/4/11**

"outline three ways materials move across a plasma membrane"
