Sample Lebanese University Faculty of Medical Sciences Entrance Examination — Second Year, General Medicine Practice Questions

Try these sample questions to review concepts for the Lebanese University Faculty of Medical Sciences Entrance Examination — Second Year, General Medicine exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which statement correctly describes the operational stoichiometry and electrogenic nature of the human plasma membrane Na+/K+ ATPase?
A.It exports 3 Na+ ions and imports 2 K+ ions per hydrolyzed ATP molecule, generating a net outward positive current.
B.It imports 3 Na+ ions and exports 2 K+ ions per hydrolyzed ATP molecule, maintaining an electroneutral exchange.
C.It exports 2 Na+ ions and imports 3 K+ ions per hydrolyzed ATP molecule, generating a net inward positive current.
D.It translocates 1 Na+ for 1 K+ per ATP molecule, depending exclusively on passive proton counter-transport for electrogenicity.
Explanation: The Na+/K+ ATPase is a P-type ion translocating pump that couples the hydrolysis of one ATP molecule to the export of 3 Na+ ions and the import of 2 K+ ions against their electrochemical gradients. Because three positive charges leave the cell for every two that enter, the pump produces a net outward positive electrical current, making it inherently electrogenic and directly contributing a few millivolts to the negative resting membrane potential.
2How does cholesterol modulate mammalian plasma membrane fluidity across physiological and elevated temperature ranges?
A.It promotes spontaneous phase separation into pure gel states at 37°C by hydrolyzing unsaturated fatty acyl chains.
B.It acts as a bidirectional fluidity buffer, restricting phospholipid acyl chain mobility at elevated temperatures and preventing tight acyl packing at lower temperatures.
C.It exclusively increases membrane fluidity at all temperatures by introducing covalent cross-links between polar head groups.
D.It binds selectively to peripheral membrane proteins to destabilize integral transmembrane alpha-helices.
Explanation: Cholesterol intercalates between phospholipid molecules with its rigid steroid ring positioned alongside the proximal hydrocarbon chains and its hydroxyl group oriented toward the polar head groups. At physiological and high temperatures, its planar rigid structure hinders acyl chain rotation and lateral displacement, thereby reducing membrane fluidity and permeability; at low temperatures, it prevents fatty acid chains from packing into a crystalline crystalline gel phase, thus preserving membrane fluidity.
3The secondary active apical uptake of D-glucose across enterocytes via SGLT1 is thermodynamically driven by which direct driving force?
A.Direct covalent phosphorylation of glucose by hexokinase at the extracellular surface.
B.The exergonic cleavage of luminal GTP by an intrinsic apical GTPase domain.
C.The downhill electrochemical gradient of Na+ maintained by the basolateral Na+/K+ ATPase.
D.A counter-transport outward flux of intracellular potassium down its chemical gradient.
Explanation: SGLT1 is a secondary active symporter that couples the thermodynamically uphill transport of D-glucose against its chemical gradient to the energetically downhill entry of two Na+ ions. This downhill movement is powered by the steep inward electrochemical sodium gradient continuously established and sustained by basolateral primary active Na+/K+ ATPase pumps.
4In neuronal axonal transport, what defines the structural polarity and molecular motor specificity of fast vesicular transport?
A.Microtubules have minus ends directed toward the axon terminal, with dynein mediating anterograde delivery.
B.Actin filaments span the entire axon length, with myosin V acting as the sole long-distance retrograde motor.
C.Intermediate neurofilaments undergo constant treadmilling to pull synaptic vesicles toward the soma.
D.Microtubules have plus ends oriented toward the synapse, where kinesin-1 mediates anterograde transport and cytoplasmic dynein mediates retrograde transport.
Explanation: Axonal microtubules exhibit uniform unipolar orientation, with their dynamic plus ends directed toward the axon terminal (synaptic bouton) and their stable minus ends anchored near the centrosome in the cell body. Kinesin-1 motors utilize ATP hydrolysis to walk processively toward the plus end, driving anterograde transport of synaptic vesicle precursors and organelles, whereas cytoplasmic dynein (assisted by dynactin) walks toward the minus end, driving retrograde transport of endosomes and neurotrophic signals to the soma.
5During actin filament treadmilling at steady state in vitro, which biochemical condition is satisfied?
A.The free G-actin monomer concentration lies between the critical concentration of the plus (barbed) end and the minus (pointed) end.
B.ATP-G-actin binds with equal kinetic association constants to both ends while ADP-actin remains covalently bonded to cofilin.
C.The pointed end exhibits a lower critical concentration than the barbed end, driving net assembly at the minus end.
D.Hydrolysis of ATP occurs immediately prior to monomer incorporation at the barbed end.
Explanation: Actin treadmilling occurs when the concentration of free ATP-G-actin is intermediate between the critical concentrations of the two ends (Cc(barbed) < [G-actin] < Cc(pointed)). Under this condition, the barbed end experiences net subunit addition because the monomer concentration exceeds its low critical concentration, while the pointed end experiences net subunit dissociation because the monomer concentration is below its higher critical concentration.
6Which post-translational modification directly triggers the disassembly of the nuclear lamina during eukaryotic mitotic prophase?
A.Ubiquitination of lamin B by the anaphase-promoting complex targeting it for proteasomal degradation.
B.Phosphorylation of nuclear lamins A, B, and C by Cyclin B-CDK1 (MPF).
C.Acetylation of lysine residues in the lamin rod domain by p300/CBP acetyltransferases.
D.Dephosphorylation of lamin globular heads by protein phosphatase 1 (PP1).
Explanation: At the onset of mitosis, activated Cyclin B-CDK1 (mitosis-promoting factor) phosphorylates specific serine residues in the amino-terminal and carboxy-terminal non-alpha-helical domains of lamins A, B, and C. This introduction of negative charges disrupts the electrostatic interactions stabilizing lamin coiled-coil dimers and tetramers, causing depolymerization of the fibrous nuclear lamina meshwork into soluble dimers and vesicle-associated fragments, leading to nuclear envelope breakdown.
7At the eukaryotic G1/S restriction point, passage into DNA replication is governed primarily by which molecular cascade?
A.Dephosphorylation of the retinoblastoma protein (Rb) by calcineurin, which silences downstream E2F transcription factors.
B.Direct degradation of p53 by the proteasome in response to double-stranded DNA breaks.
C.Hyperphosphorylation of the retinoblastoma protein (pRb) by Cyclin D-CDK4/6 and Cyclin E-CDK2, releasing E2F transcription factors.
D.Binding of unphosphorylated pRb to the origin recognition complex to activate MCM2-7 helicase loading.
Explanation: In early G1, hypophosphorylated retinoblastoma protein (pRb) binds tightly to E2F transcription factors and recruits histone deacetylases, actively repressing genes required for DNA synthesis. Mitogenic signaling upregulates Cyclin D-CDK4/6 complexes, which initiate pRb phosphorylation; subsequent hyperphosphorylation by Cyclin E-CDK2 causes a conformational change that forces pRb to dissociate from E2F, allowing E2F to transcribe genes essential for S-phase entry, including DNA polymerase, thymidine kinase, and Cyclin A.
8What enzymatic switch controls the abrupt activation of the mitotic Cyclin B-CDK1 complex at the G2/M transition?
A.Permanent proteolytic cleavage of CDK1 by caspase-3.
B.Phosphorylation of Thr14 and Tyr15 on CDK1 by CAK (CDK-activating kinase).
C.Ubiquitin-mediated degradation of Cyclin B by the Skp1-Cullin-F-box (SCF) complex.
D.Dephosphorylation of inhibitory residues Thr14 and Tyr15 on CDK1 by the dual-specificity phosphatase Cdc25.
Explanation: During G2, Cyclin B accumulates and associates with CDK1, but the complex is held in an inactive state by Wee1 and Myt1 kinases, which phosphorylate inhibitory residues Thr14 and Tyr15 within the ATP-binding pocket. At the G2/M transition, the dual-specificity phosphatase Cdc25C removes these inhibitory phosphates, rapidly activating Cyclin B-CDK1. Active CDK1 then phosphorylates Cdc25 to activate it and Wee1 to inhibit it, creating a robust bistable positive feedback loop that drives the cell into mitosis.
9Which mechanism enforces the spindle assembly checkpoint (SAC) to prevent premature anaphase onset when unattached kinetochores are present?
A.Unattached kinetochores generate a diffusible Mad2-BubR1-Bub3-Cdc20 complex (mitotic checkpoint complex) that inhibits APC/C activity.
B.Unattached kinetochores directly activate separase to cleave cohesin complexes along chromosome arms.
C.Centromeric dynein motors dephosphorylate securin, preventing its association with the 26S proteasome.
D.Aurora B kinase phosphorylates tubulin dimers to immediately disassemble all astral microtubules.
Explanation: Unattached kinetochores recruit SAC proteins including Mad1, which catalyzes the conformational change of open Mad2 to closed Mad2. Closed Mad2 forms the mitotic checkpoint complex (MCC) together with BubR1, Bub3, and Cdc20. The MCC acts as a pseudo-substrate inhibitor of the anaphase-promoting complex/cyclosome (APC/C), preventing it from polyubiquitinating securin and Cyclin B until every single kinetochore has achieved stable bipolar attachment and tension under the mitotic spindle.
10In the intrinsic (mitochondrial) pathway of apoptosis, which molecular assembly constitutes the active apoptosome?
A.Fas ligand, Fas receptor, FADD adapter, and procaspase-8.
B.Cytochrome c, Apaf-1, dATP/ATP, and procaspase-9.
C.Bcl-2, Bax, Bad, and caspase-12.
D.Perforin, granzyme B, BID, and procaspase-3.
Explanation: Pro-apoptotic stimuli induce mitochondrial outer membrane permeabilization (MOMP) via Bax/Bak oligomers, releasing cytochrome c into the cytosol. Soluble cytochrome c binds to the WD40 repeats of apoptotic protease activating factor-1 (Apaf-1), inducing a dATP/ATP-dependent conformational change that oligomerizes Apaf-1 into a heptameric wheel-like complex known as the apoptosome. The caspase recruitment domains (CARD) of the apoptosome recruit and dimerize procaspase-9, activating it to cleave downstream executioner caspases-3 and -7.
