PPT-Key Area 1.3 Membrane Proteins

Unit 1 Cells and Proteins Advanced Higher Biology Miss Aitken Recap on the Cell Membrane In N5 we learned that the membrane of cells is made up of a bilayer of phospholipids with proteins embedded in the layers. Essential idea: The structure of biological membranes makes them fluid and dynamic.. Above . are models of a plasma membrane showing how it's fluidity allows lipid soluble molecules to move directly through the membrane.. Ch. 12, . Stryer. Short Course. Introduction to Membranes. Lipid structure makes a bilayer. Hydrophobic effect. Non-covalent structure. Fluidity of membrane: liquid crystal. Fluidity controlled by cholesterol, tail packing. Different types of . mb. proteins require different conditions for . mb. release. Integral membrane proteins directionally insert in the membrane bilayer. Outside cell. Inside cell. Glycophorin. and . All organisms are made of cells. Cell structure is correlated to cellular function. All cells are related by their descent from earlier cells. The Fundamental Units of Life. to study cells. Though usually too small to be seen by the unaided eye, cells can be complex. Light microscopes are commonly used in classrooms. Living cells can be examined. The downfall is that they do not magnify a tremendous amount. . 2. Magnification. . is the ratio of an object’s image to its real size. A light microscope can magnify effectively to about 1,000 times the real size of a specimen. . Chapter 7. Carbohydrates. Of the macromolecules that we will cover in this class, those involving carbohydrates are the most abundant in nature.. Via photosynthesis, over 100 billion metric tons of CO. Cell structure and Function . in Bacteria and Archaea. 1. Cell Shape and Size. 2. The . cytoplasmic. membrane and Transport. 3. Cell walls of prokaryotes. 4. Other Cellular Surface structures and inclusions. (mitochondria and . peroxisomes. ). Dr. Mamoun Ahram. Faculty of Medicine. Second year, Second semester, 2014-2014. Principles of Genetics and Molecular Biology. What are the mitochondria?. Mitochondria are thought to have evolved from bacteria via . Plasma membranes :. Membranes. cover the surface of every cell and also surround most organelles within cells. They have a number of functions, such as:. keeping all cellular components inside the cell. Intracellular Compartments: Endoplasmic Reticulum and Protein Sorting Golgi Apparatus and Intracellular Vesicular Traffic Assist. Prof. Dr. Pinar Tulay , Ph.D . Faculty of Medicine Department of Me Module 1: Components a nd Architecture o f Cell Membrane Learning objectives: In this module, prime focus is mainly on the plasma membrane, however, majority of the concepts discussed below are also S.J. Singer and Garth L. Nicolson proposed the fluid mosaic model , which is widely used.. The fluid mosaic model of the plasma membrane structure describes the plasma membrane as a fluid combination of phospholipids, cholesterol, proteins, and carbohydrates.. 2+. Cell Membrane . Fluid Mosaic Model . Cell membrane is thought to be both fluid and a mosaic of phospholipids, proteins and carbohydrates. . Fluid .  material is capable of flowing, changing shape, and shifting. Unit 1 Advanced Higher. Miss Aitken. Pages 16-25. Textbook. Proteomics. Genome:. complete set of DNA. Comprises of coding and non-coding areas. 20-25000 genes in human genome. Proteome:. Entire set of proteins that can be expressed from a genome.
