Applied Pathophysiology A Conceptual Approach to the Mechanisms of Disease 3rd Edition Braun Test BANK Applied Pathophysiology A Conceptual Approach to the Mechanisms of Disease 3rd Edition Braun T est BankChapter 1Introduction to Pathophysiology 1.The nucleus _________, which is essential for function and survival of the cell.A)is t he site ofprotein synthesisB)contains t he genetic codeC) transforms cellular energyD)initiates aerobic metabolism2.Although e nergy is not made in mitochondria, they are known as the powerplants of the cell b ecause t hey:A)contain RNA for protein synthesis.B)utilize glycolysis for oxidative energy.C)extract energy f rom organic compounds.D)store calcium bonds for muscle contractions.3.Although t he basic structure of the cell plasma membrane is f ormed by a lipidbilayer, most of the specific membrane functions are carried out by:A)bound and transmembrane proteins.B)complex, l ong carbohydrate chains.C)surface antigens and hormone receptors.D)a gating system of selective i on channels.4.To effectively relay signals, cell-to-cell c ommunication utilizes chemicalmessenger systems that:A)displace surface receptor proteins.B)accumulate within cell gap junctions.C)bind to contractile microfilaments.D)release secretions into extracellular fluid.5.Aerobic metabolism, also known as oxidative metabolism, provides energy by: A)removing the phosphate bonds from ATP.B)combining hydrogen a nd o xygen to f orm water.C)activating pyruvate stored in the cytoplasm.D)breaking down glucose to f orm lactic acid.6.Exocytosis, the reverse of endocytosis, is important in _______ into the extracellular fluid.A)Engulfing and i ngesting fluid and proteins for transportB)Killing, degrading, and dissolving harmful microorganismsC)Removing cellular debris andreleasing synthesized substancesD)Destruction of particles by lysosomal enzymes for secretion7.The process responsible for generating a nd conducting membrane potentials is:A)diffusion of current-carrying ions.B)millivoltage of electrical potential.C)polarization of charged particles.D)ion channel neurotransmission.8.Epithelial tissues are classified a ccording to the shape of the cells and t he number of layers. Which of the following i s a correctly matched description and t ype of epithelial tissue?A)Simple epithelium: cells in c ontact with intercellular matrix; some do n ot extend to s urfaceB)Stratified epithelium: single layer of cells; a ll cells rest on basement membraneC)Glandular epithelium: arise from surface epitheliaand u nderlying connective tissueD)Pseudostratified e pithelium: multiple layers of cells; deepest layer rests onbasement membrane9.Connective tissue contains fibroblasts t hat are responsible for:A)providing a fibrous f ramework for capillaries.B)synthesis o f collagen, elastin, and reticular fibers
