The enzymatic reaction catalyzed by amylase primarily breaks down which polysaccharide?
सही उत्तर: ख) B. Starch
Amylase specifically hydrolyzes alpha-1,4 glycosidic bonds in starch molecules to form smaller sugars like maltose and glucose. Option B is the correct answer; options A, C, and D are polysaccharides that amylase does not effectively break down.

Which cellular process is MOST directly responsible for maintaining glucose homeostasis within cells?
सही उत्तर: घ) D. Protein synthesis
Insulin promotes the translocation of GLUT4 transporters to the cell membrane, allowing glucose from the bloodstream to enter the cell and be utilized. Option A is a solvent process, not directly involved in glucose management. Option B is the breakdown of glucose, not its uptake. Option D is unrelated to glucose homeostasis.

The glomerular filtration rate (GFR) is directly influenced by which of the following factors?
सही उत्तर: ग) C. Elevated venous pressure within the glomerulus
GFR is primarily determined by the hydrostatic pressure difference across the glomerular capillaries (afferent vs. efferent) and the colloid osmotic pressure of proteins in Bowman's capsule. Option A increases capillary resistance, decreasing GFR. Option C elevates venous pressure, also reducing GFR. Option D would have a slight effect but not the primary driver.

A pregnant woman presents with a sudden onset of severe lower abdominal pain, vaginal bleeding, and signs of hypovolemic shock. Initial assessment reveals fetal tachycardia and fetal distress. What is the immediate priority?
सही उत्तर: ख) Initiate induction of labour
An emergency Cesarean section (option 1) is the priority in this situation due to the high risk of fetal demise and maternal morbidity associated with a ruptured uterus. While fluids, induction, and oxytocin might be part of the overall management, immediate delivery of the baby is crucial.

In a newborn diagnosed with Down Syndrome, which of the following maternal serum markers would typically be elevated?
सही उत्तर: ग) Triple Marker Panel (TFP)
The Triple Marker Panel (TFP) (option 2) consistently shows elevated levels of free beta-hCG and trisomy 21 related markers in pregnancies affected by Down Syndrome. While hCG is generally elevated in pregnancy, it’s the combination with other TFP components that is diagnostic.

What is the primary diagnostic criterion for diagnosing Cystic Fibrosis based on pulmonary function tests?
सही उत्तर: क) Reduced FEV1/FVC ratio
A reduced FEV1/FVC (Forced Expiratory Volume in 1 second / Forced Vital Capacity) ratio (option 0) is a hallmark finding in Cystic Fibrosis due to airway obstruction. The other options represent normal or atypical pulmonary function results.

A 6-year-old boy presents with chronic diarrhea, abdominal pain, and failure to thrive. Examination reveals a palpable intestinal mass. Which of the following is the MOST likely diagnosis?
सही उत्तर: ग) Hirschsprung's Disease
Hirschsprung’s disease (option 2) is characterized by an absence of ganglion cells in the distal colon, leading to a palpable intestinal mass and chronic constipation/diarrhea. While Celiac disease, IBD, and microscopic colitis can cause similar symptoms, they typically don't present with a palpable mass.

Which of the following conditions is MOST commonly associated with the ‘scorbutic rosary’ presentation in infants?
सही उत्तर: ग) Scurvy
Scurvy (option 2) classically presents with subperiosteal hemorrhages leading to ‘pseudoparalysis’ and the characteristic 'scorbutic rosary'. The other options – Vitamin D deficiency, Iron deficiency anemia, and Zinc deficiency – can cause various symptoms but don't directly manifest as this specific skeletal finding.

-
Which enzyme plays a crucial role in converting triglycerides into fatty acids?
सही उत्तर: घ) CoA Reductase
CoA reductase is the key enzyme involved in beta-oxidation, the process where triglycerides are broken down to produce acetyl-CoA and fatty acid molecules. The other enzymes are involved in different lipid metabolism pathways.

A researcher measures the concentration of glucose in serum samples from patients with diabetes. A value of 180 mg/dL indicates what?
सही उत्तर: ग) Established Diabetes
A serum glucose level of 180 mg/dL typically falls within the range considered indicative of a prediabetic state. This is based on established diagnostic criteria for diabetes and impaired fasting glucose, reflecting elevated blood sugar levels. The other options represent different glycemic ranges.
