Ch.7 Notes and Lecture Date Notes Questions 10/7/15 Unless something there is something non soluble only a helper protein can help it get through Phospholipid Bilayer Endocytosis is when a cell membrane can take/release atoms. Fatty acid tails will not associate with ions Diffusion when high concentration to low concentration Active Transport Learn proteins on the membrane Proteins make membrane selectively permeable 10/8/15 Passive transport, know all forms Diffusion as well Water can pass directly though phospholipid membrane Pores allow passage for chemicals to enter the cell. Diagram, #1 Facilitated diffusion: Use of proteins on the membrane to take in and put out chemicals. Osmosis: diffusion of water through selectively permeable barrier. Diagram 2
