Membranes, Membranes, Membranes

We started today with a review of what we talked about yesterday (ATP, phosphorylation, how a protein is formed) before moving forward. Through the beauty of YouTube we watched several short clips that summed up the information in various sections in the book.

C Block: For Lab tomorrow you need to take notes on the osmosis animations seen here. These notes should go in your class notebook (this is the material we did not get to today).

5.10 Membranes organize the chemical activities of cells
5.11 Membrane phospholipids form a bilayer
5.12 The membrane is a fluid mosaic of phospholipids & proteins

5.14 Passive transport is diffusion across a membrane

5.13 Proteins make the membrane a mosaic of function
5.17 Transport proteins facilitate diffusion across membranes

Lastly we used these animations (click the picture to be taken to the link) to learn about osmosis, hypertonic, hypotonic and isotonic solutions (sections 5.15 and 5.16)
