WARM UP!!!!! Take a sheet of note book paper out and write down a few ideas down about these questions. (work quietly, by YOURSELF) Name some organelles in the cell What is cell transport? What is active transport? What is passive transport?

CELL MEMBRANE AND TRANSPORT

THE CELL MEMBRANE Separates the interior of all cells from the outside enviroment Selectively permeable  Controls movement in and outside of cells

WHAT IT IS MADE OF LIPIDS DOUBLE LAYER OF PHOSPHOLIPIDS

WHAT IT IS MADE OF… PROTEINS Fibrous Globular-shaped

PROTEINS…what do they do? Transport chemicals and information across the membrane Integral proteins (transmembrane) Lipid anchored proteins Peripheral proteins

ACTIVE TRANSPORT Movement of a substance against its concentration gradient From low to high concentration USES ENERGY

PASSIVE TRANSPORT Moving biochemical and atomic or molecular substances across the membrane NO ENERGY Depends on the permeability(rate of passage) of the membrane

BUBBLES!!!!!!

ANSWERS

Plasma Bilayer Selectively permeable Energy Active transport Integral Peripheral transmembrane
