Sample Concours PACES Vétérinaire Practice Questions

Try these sample questions to review concepts for the Concours PACES Vétérinaire exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 96+ question experience with AI tutoring.

1Under anaerobic conditions in mammalian erythrocytes or working skeletal muscle fibers, what is the net yield of ATP generated per molecule of glucose oxidized via the glycolytic pathway?
A.1 ATP
B.2 ATP
C.4 ATP
D.32 ATP
Explanation: Anaerobic glycolysis consumes 2 ATP molecules in the preparatory phase (catalyzed by hexokinase and phosphofructokinase-1) and generates 4 ATP molecules in the payoff phase via substrate-level phosphorylation (catalyzed by phosphoglycerate kinase and pyruvate kinase). This yields a net gain of 2 ATP per glucose molecule, with NADH reoxidized by lactate dehydrogenase to regenerate NAD+.
2What is the net ATP yield from the complete beta-oxidation and subsequent aerobic oxidation (via the citric acid cycle and electron transport chain) of one molecule of palmitic acid (C16:0)?
A.106 ATP
B.129 ATP
C.96 ATP
D.140 ATP
Explanation: Palmitate (16 carbons) undergoes 7 cycles of beta-oxidation, producing 7 FADH2 (7 x 1.5 = 10.5 ATP), 7 NADH (7 x 2.5 = 17.5 ATP), and 8 acetyl-CoA. The 8 acetyl-CoA entering the TCA cycle yield 8 x 10 = 80 ATP. Total gross yield is 10.5 + 17.5 + 80 = 108 ATP. Subtracting 2 high-energy phosphate equivalents for acyl-CoA activation (ATP -> AMP + PPi) gives a net yield of 106 ATP.
3In the hepatic urea cycle of domestic mammals, which enzyme catalyzes the initial rate-limiting step inside the mitochondrial matrix, requiring N-acetylglutamate as an essential allosteric activator?
A.Ornithine transcarbamylase
B.Argininosuccinate synthetase
C.Arginase
D.Carbamoyl phosphate synthetase I
Explanation: Carbamoyl phosphate synthetase I (CPS I) is located in the mitochondrial matrix of hepatocytes. It catalyzes the condensation of ammonia (NH4+), bicarbonate (HCO3-), and 2 ATP to form carbamoyl phosphate. CPS I is the committed and rate-limiting enzyme of ureagenesis and strictly requires N-acetylglutamate (NAG) as an allosteric activator.
4In the fluid mosaic model of mammalian plasma membranes, what is the primary role of cholesterol in modulating membrane fluidity across physiological temperatures?
A.It binds to extracellular ligands to trigger secondary messenger cascades
B.It acts as a bidirectional fluidity buffer, restraining phospholipid movement at high temperatures and hindering tight packing at low temperatures
C.It forms covalent cross-links between transmembrane protein alpha-helices to rigidify the bilayer
D.It creates active hydrophilic pores allowing passive water and electrolyte transit
Explanation: Cholesterol functions as a bidirectional fluidity buffer in animal cell membranes. At high temperatures (e.g., physiological body temperature ~37-39°C in domestic animals), its rigid steroid ring system interferes with phospholipid acyl chain movement, reducing membrane fluidity. At lower temperatures, its bulky structure disrupts the close parallel packing and crystallization of hydrocarbon chains, lowering the phase-transition temperature.
5During the synthesis of secretory and lysosomal proteins in domestic animal cells, which ribonucleoprotein particle recognizes the hydrophobic N-terminal signal sequence and halts translation until docking onto the rough endoplasmic reticulum?
A.Ribophorin I
B.Clathrin coatomer
C.Signal Recognition Particle (SRP)
D.Proteasome 26S
Explanation: The Signal Recognition Particle (SRP) is a cytosolic ribonucleoprotein complex consisting of 7SL RNA and 6 distinct polypeptides. It binds to the hydrophobic N-terminal signal peptide as it emerges from the ribosome exit tunnel, temporarily arresting translation elongation. SRP then guides the ribosome-nascent chain complex to the SRP receptor on the cytosolic face of the rough ER membrane, transferring it to the Sec61 translocon pore.
6Which specific biochemical modification added in the cis-Golgi apparatus targets newly synthesized acid hydrolases to the lysosome rather than the constitutive secretory pathway?
A.C-terminal KDEL peptide signal addition
B.Ubiquitin polymerisation via Lys48 linkages
C.GPI anchor attachment to the C-terminus
D.Phosphorylation of mannose residues to mannose-6-phosphate (M6P)
Explanation: Acid hydrolases targeted to lysosomes are specifically tagged in the cis-Golgi network by UDP-N-acetylglucosamine phosphotransferase, which transfers N-acetylglucosamine-1-phosphate to specific mannose residues on N-linked oligosaccharides. A second enzyme removes the GlcNAc, exposing the mannose-6-phosphate (M6P) recognition tag. In the trans-Golgi network, transmembrane M6P receptors bind these enzymes, packaging them into clathrin-coated transport vesicles directed toward late endosomes.
7In the eukaryotic cell cycle, the Maturation-Promoting Factor (MPF) that triggers the transition from the G2 phase into mitosis (M phase) is a heterodimer composed of which two molecules?
A.Cyclin B and CDK1 (Cdc2)
B.Cyclin D and CDK4/6
C.Cyclin E and CDK2
D.Cyclin A and CDK2
Explanation: Maturation-Promoting Factor (MPF), also designated as M-phase promoting factor, is a conserved serine/threonine kinase complex formed by the association of regulatory subunit Cyclin B and catalytic subunit CDK1 (formerly Cdc2). Activation of CDK1 via dephosphorylation by Cdc25 phosphatase at the end of G2 phase triggers chromosome condensation, nuclear envelope breakdown, and mitotic spindle assembly.
8In the intrinsic (mitochondrial) pathway of apoptosis in mammalian cells, which event directly triggers the assembly of the apoptosome in the cytosol?
A.Binding of Fas ligand (FasL) to the Fas death receptor (CD95)
B.Release of cytochrome c from the mitochondrial intermembrane space into the cytosol and its binding to Apaf-1
C.Direct nuclear translocation of caspase-8 to cleave chromatin
D.Inhibition of the transcription factor p53 by MDM2
Explanation: In response to cellular stress, DNA damage, or growth factor deprivation, pro-apoptotic Bcl-2 family members (Bax/Bak) oligomerize in the outer mitochondrial membrane, forming pores that release cytochrome c from the intermembrane space into the cytosol. Cytosolic cytochrome c binds apoptotic protease activating factor-1 (Apaf-1) in the presence of dATP/ATP, inducing Apaf-1 heptamerization into the wheel-like apoptosome, which recruits and activates initiator procaspase-9.
9Which type of epithelium lines the luminal surface of the mammalian trachea and primary bronchi, functioning in the mucociliary clearance apparatus?
A.Simple squamous epithelium
B.Stratified squamous non-keratinized epithelium
C.Pseudostratified ciliated columnar epithelium with goblet cells
D.Transitional epithelium (urothelium)
Explanation: The respiratory conducting passages (nasal cavity, trachea, and major bronchi) are lined by pseudostratified ciliated columnar epithelium interspersed with mucus-secreting goblet cells (often termed respiratory epithelium). All cells contact the basal lamina (hence 'pseudostratified'), but nuclei are positioned at varying levels. Cilia beat metachronously toward the pharynx, sweeping trapped airborne particulates out of the respiratory tree.
10Which fibrillar collagen type is the predominant structural protein providing tensile strength in domestic animal tendons, ligaments, and dense regular connective tissues?
A.Collagen type I
B.Collagen type II
C.Collagen type III
D.Collagen type IV
Explanation: Collagen type I is the most abundant collagen in domestic mammals, comprising over 90% of the body's collagen content. It forms thick, striated, parallel-oriented fibrils with high tensile strength in tendons, ligaments, bone matrix (osteoid), aponeuroses, and the dermis of the skin.

About the Concours PACES Vétérinaire Exam

Independent PACES Vétérinaire practice covering retained biological, biophysical, pharmacological, animal-physiology, and domestic-mammal anatomy concepts. Use it with current Faculty notices and course materials.

Exam sponsor: Faculté de Médecine, Université d'Antananarivo. The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Assessment

PACES ends in competitive ranking under numerus clausus, with common teaching units and pathway-specific assessment. The veterinary UE8 is a written QCM assessment covering animal physiology (the internal environment and excitable tissues) and anatomy of domestic mammals; other Faculty materials describe unit-dependent QCM and written questions. The reviewed materials are in French, but no separate official language rule was found. This English four-option MCQ bank is an independent conceptual adaptation, not an official translation, paper-layout simulation, or substitute for written, diagrammatic, or other required work.

Time Limit

No consolidated duration published; the official veterinary UE8 outline gives 45 minutes to 1 hour for that unit.

Passing Score

Competitive ranking under numerus clausus; 10/20 validates the published veterinary UE8 credits but is not by itself a current L2 selection cutoff.

Exam / Certification Fees

Not published for the end-of-PACES concours; 50,000 Ariary is the separate current L1 dossier pre-registration fee.
