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

Ch. 6 AP Bio Lecture Date Notes Questions 9/29 Multicellular organisms, many cell types, specialized tasks Single cell, singular task done for survival Body is like ecosystem 80% cells are microbes that live in gut Signaling is essential for multicellular organisms Big Brain Theory ? Mutations made so many times that the cells could send signals in so many different ways White Blood Cells stick to walls of Arteries Tumble of surface while red blood cells move as fluids. White Blood Cells Like Velcro Signals change that, proteins that make them less sticky so that they can move to areas where there is damage or stickiness when not being used. Done so that signals are efficiently received. Microtubules contribute to the cytoskeleton

Gavin Morgan 10/9/2015 Chapter 5 2-Point Notes The fluid mosaic model shows proteins embedded in a fluid lipid bilayer: 1. The lipid layer that forms the foundation of a cell?s membranes is a bilayer formed of phospholipids. 2. Globular proteins are inserted into the lipid bilayer, with their nonpolar segments in contact with the nonpolar interior of the bilayer and their polar portions protruding out from the membrane surface. Cellular membranes consist of four component groups: 1. A eukaryotic cell contains many membranes. 2. Cell membranes are assembled from: Phospholipid bilayers, transmembrane proteins, interior protein networks, and cell-surface markers.

Membrane Structure and Function Chapter 7 Overview: Life at the Edge The plasma membrane is the boundary that separates the living cell from its surroundings The plasma membrane exhibits selective permeability, allowing some substances to cross it more easily than others ? 2011 Pearson Education, Inc. Figure 7.1 Concept 7.1: Cellular membranes are fluid mosaics of lipids and proteins Phospholipids are the most abundant lipid in the plasma membrane Phospholipids are amphipathic molecules, containing hydrophobic and hydrophilic regions The fluid mosaic model states that a membrane is a fluid structure with a ?mosaic? of various proteins embedded in it ? 2011 Pearson Education, Inc.

AP Reading Guide Chapter 7: Membrane Structure and Function Fred and Theresa Holtzclaw Name_______________________Period___________ Chapter 7: Membrane Structure and Function Concept 7.1 Cellular membranes are fluid mosaics of lipids and proteins 1. The large molecules of all living things fall into just four main classes. Name them. 2. Explain what is meant when we say a molecule is amphipathic. 3. In the 1960s, the Davson-Danielli model of membrane structure was widely accepted. Describe this model and then cite two lines of evidence that were inconsistent with it. 4. Who proposed the fluid mosaic model of membrane structure? When? Describe this model.
