Exam 2 Study Guide Terms Peptidoglvcan a polymer composed of sugars and proteins Endospore a protective mechanism formed around the bacterial chromosomes in periods of stress Plasmid small circular piece of DNA that is kept inside the bacteria cell that carries a small number of genes and can be readily acquired by other cells Light Microscopy LM a microscope where visible light is passed through the cell and then through glass lenses Electron Microscopy EM a microscope that focuses a beam of electrons through the cell or onto its surface Scanning EM used to view the cell s surface by re ecting electrons off of the surface which is usually coated with a substance Transmission EM used to view the cell s interior Lipid Membrane a bi layer with phospholipid heads on the outside and the hydrophobic tails on the inside Passive Transport transport across the membrane that does not require energy Diffusion the passive movement of any substance down its concentration gradient Facilitated Diffusion the movement of molecules across the membrane with the aid of transport proteins Active Transport transport across a membrane that requires energy Ligand any molecule that binds specifically to a receptor site on another molecule Loss of Function Mutation a mutation that prevents a protein from having its intended effect Proteolysis the hydrolysis of peptide chains in a highly controlled manner Proteasome the complex that houses proteolysis Concepts 0 09 Bacteria Prokaryotic Features Cell Wall Features Capsules Peptidoglycan layer Fimbriae Taxis Flagella Gram Staining Gram positive Color Cell wall layers 2 Gram negative Color Cell wall layers 3 Cell Organization DNA Endospores Reasons Behind Genetic Diversity Rapid division Genetic transfer Conjugation Requirements F factors F cell donor Hfr cell donor Transduction Definition Example Transformation Definition Experimental research Antibiotics Resistance How they work 339 Cells 2 Techniques Cell fractionation Microscopy Light microscopy Electron Microscopy Scanning Transmission Prokaryotes vs Eukaryotes Similarities Differences Eukaryotes Plants Animals Organelles Function Examples Membranes Functions Endomembrane System Components Nuclear envelope ER Golgi body Lysosomes Vacuoles Plasma membrane Trafficking vesicles Functions Endosymbiotic Theory Mitochondria Chloroplasts Cytoskeleton Functions Types of Fibers Microfilaments Microtubules Intermediate filaments 339 Membranes Lipids Hydrocarbons Isomers Fats Triacy1g1ycerol Saturated vs Unsaturated Fats Characteristics Origins Trans Fat Origin Effect on the body Phospholipids 2 regions Lipid Bilayers Orientation Fluid mosaic model Factors that affect uidity Membrane Permeability Polar vs nonpolar molecules Types of molecules that easily cross the membrane Types of molecules that need assistance crossing the membrane Membrane Transport Passive transport Diffusion Facilitated diffusion Active transport Channel proteins Definition Examples Carrier proteins Definition Examples 339 Cell Signaling Types of Differentiated Cells Functions MSCs Stem Cells vs Differentiated Single genome Cell division Overview Stage 1 signal receiving Stage 2 signal transduction Stage 3 cellular response Signal Transduction Kinase Phosphatase Signal Shut Down Activation Events prior when does it shut down Signal Amplification Expansion of signal Membrane Protein Recycling Receptor mediated endocytosis
