| Integral Arrangment of Membrane Protein |
extends into or across bilayer clothespin |
| Peripherial Arrangment of protein |
loosely attached to inner and outer surface |
| What is Tonicity |
measure of solutions ability to change the volume of cells by altering there H20 |
| what is isotonic |
normal shape |
| what is hypertonic |
there is more concentration inside than outside |
| what is hypotonic |
when concentration is higher outside than inside |
| Simple Diffusion |
is when the FA is passed through polar head and tail no NRG is expended |
| Facilitated Diffusion |
Glucose passes through pores, pores change shape to accept no NRG is expended |
| Active Transport |
NaK pump, NRG is used to move 3Na out 2 K |
| What is endocytosis |
