PPT-Advanced Higher Cells and Proteins

Dna Proteins and Binding to ligands Think What proteins are associated with DNA How are proteins involved in transcription How is protein production controlled Why is it important that protein production is controlled. Introduction:. Plasma proteins are:. Serum albumin.. Serum globulin.. Fibrinogen.. Serum contains albumin and globulin.. Fibrinogen is absent . Converted into fibrin during blood clotting.. Therefore albumin and globulin are called serum albumin and serum globulin.. Fluorescence Technology. Josh Leung. James Weis. February 18th, 2010. Bio 1220, Gary Wessel. Fluorescence: How does it work?. Fluorescence vs Phosphorescence. -Time delay – microsecond vs min. Photon absorbed → photon released. Before we begin, . what are . organelles. ?. Cells organelles. If we have “organs”, cells have …. Organelles: Specialized parts of the cell . . . . with specific functions. Cells organelles. Dr. Mamoun Ahram. Faculty of Medicine. Second year, Second semester, 2014-2014. Principles of Genetics and Molecular Biology. The extracellular matrix. What is it?. The extracellular matrix fills the spaces between cells and binds cells and tissues together. Types:. What 3 components make up the cell theory? . Where is the DNA housed in a eukaryotic cell? . How do organelles in a cell compare to organs in the human body? . Learning Target . “I can” analyze the difference between a prokaryotic cell and a eukaryotic cell. . Ligand. In biochemistry and pharmacology, a ligand is a substance that forms a complex with a biomolecule to serve a biological purpose. In protein-ligand binding, the ligand is usually a molecule which produces a signal by binding to a site on a target protein. The binding typically results in a change of conformation of the target protein.. 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. . Lipids and Nucleic Acids. NC Essential Standard Bio.4.1. Organic Molecules. Large compounds or macromolecules that contain carbon. Required by all living things. 4 Organic Molecules:. Carbohydates, Lipids, Proteins, and Nucleic Acids. Polypeptides . are chains of amino acids linked together by condensation reactions. the main, or only, component in proteins. Some proteins are composed of only one polypeptide chain, while others are made of 2 or more. Most abundant molecule in cells making up 50% or more of their dry weight. Every protein has a unique structure, or shape. Allows it to perform a specific function. Enzymes are proteins that function as catalysts for many reactions in foods. Biocompatibility and Cellular Overview Part 2. Outline . Biocompatibility. Quick overview of cellular interaction. Scale, size, generic animal cell. Nanoscale materials . for biological interaction. Liposomes. The concentration of many of these are affected by pathological processes; they are therefore measured.. They contain disulphide bonds.. Functions of plasma proteins include:. Transport. Maintaining plasma . Dr. Mustafa Jawad. Introduction. . The proteins of immune system include : . structural proteins, soluble proteins . Structural proteins . include: surface proteins such as MHC system (HLA), cytokine receptors, surface antibodies. Advanced Higher Biology. Miss Aitken. The Cell Cycle. Mitosis is the process of cell division.. Some cells are able to reproduce and make copies of themselves by following this sequence of events. The cell cycle consists of 2 phases: interphase (not dividing) and mitosis (dividing).
