1. Vertebrate Physiology Chapter 2 Sketch a cell and label the parts you sketched. On the back, give the function of each part you included in your drawing.

2. Chapter 2 Cell Physiology Demonstrate full knowledge of cell physiology. This will be measured by having the student sketch a picture of a generalized cell. Students will label, and describe the function of each part, and answer exam questions about major chemical pathways in cells and organelles.

3. What kind of cell did you draw? http://www.bioon.com/book/biology/mboc/mboc.cgi@code=220801800040279.htm http://www.bioon.com/book/biology/mboc/mboc.cgi@code=220801800040279.htm Oligodendrocyte Microglia Ependymal cell Astrocyte

12. Cytosol Outer mitochondrial membrane Intermembrane space Inner mito- chondrial membrane Low H+ Electron transport system Electrons flow through a series of electron carriers from high-energy to low-energy levels; the energy released builds an H+ gradient across the inner mitochondrial membrane. Chemiosmosis ATP synthase catalyzes ATP synthesis using energy from the H+ gradient across the membrane.
