NBME 25 QUESTIONS AND ANSWERS 100% PASS Patient had anaphylaxis following the transfusion of fresh frozen plasma. What is the genetic deficiency? IgA deficiency. Patient with this disease may have preformed antibodies against IgA How does sitagliptin work? It is a competitive inhibitor of dipeptidyl peptidase-4 (DPP4). It prevents breakdown of GI incretins (ex: glucagon-like peptide, GLP-1) and promote endogenous release of insulin. ** DPP4 inhibitor increases endogenous insulin What are acou...

Bio 151 Review Exam Questions and Answers fats and oils - Answer-super high density, long-term energy storage interaction with water defines boundaries in cells (builds membranes) sterols - Answer-act as biological signals in cells stiffen membranes maintains fluidity (prevents fatty acids from crystallizing) fatty acids - Answer-long carbon/hydrogen chains made from two-carbon units so are often made of 16 or 18 carbons fat - Answer-a large molecule constructed from 2 kinds of s...

_______________ have a single or multiple solute binding pockets and after solute binding, a reversible conformation movement exposes the solute-binding pocket to the other face of the membrane. - transporters Because of the factors affecting diffusion, H2O will move from an area of higher concentration (low osmolarity) to an area of lower concentration (higher osmolarity) if the cell membrane is permeable to H2O [6.03]. The movement of H2O in this way is a very powerful force, capable of r...

Electron microscope - ️️instrument that uses a beam of electrons instead of light to magnify structures up to 500,000 times actual size; allows scientists to view structures within a cell Aquaporin - ️️A transport protein in the plasma membrane of a plant or animal cell that specifically facilitates the diffusion of water across the membrane (osmosis). Cancer - ️️any malignant growth or tumor caused by abnormal and uncontrolled cell division Cell - ️️(biology) the basic st...

Membrane Transport What is the major difference between V-ATPase and F-ATPase? - ANSWERSV-ATPase uses ATP to pump hydrogen against the concentration gradient; F-ATPase uses hydrogen concentration gradient to make ATP Why can't H3O+ flow through an aquaporin channel? - ANSWERSH3O+ size and charge; positively charged Asn repel H3O+ How would F-ATPase be affected with H3O+ could flow through aquaporins? - ANSWERSChange H+ gradient, affecting function of F-ATPase and production of ATP How...

ADH - -increases permeability to water in cells of the distal tubule and collecting duct causing higher water reabsorption -increases aquaporin, water channels, content in the apical membrane -increases blood pressure and volume ANP - -decreases Na and water reabsorption -inhibits aldosterone and ADH release Buffering of H+ in the Urine - free H+ can be reabsorbed through a pump therefore we want it to bind to something Colloid Osmotic Pressure (COP) - -osmolarity of plasma proteins -25...

Actin A globular protein that links into chains, two of which twist helically about each other, forming microfilaments (actin filaments) in muscle and other kinds of cells. Active transport The movement of a substance across a cell membrane, with an expenditure of energy, against its concentration or electrochemical gradient; mediated by specific transport proteins. Adenosine triphosphate (ATP) An adenine-containing nucleoside triphosphate that releases free energy when its phosphate bonds are...
