Biochemistry is a core part of the PMDC NLE syllabus. HighYield's Biochemistry question bank collects 6MCQs modelled on real past papers, so you practise the exact style and difficulty you'll face on exam day. Every question comes with a worked explanation and a subject reference, so you learn why an answer is right — not just which option to pick.
Work through Biochemistry in Tutor mode to learn as you go, or switch to Timed mode to simulate real exam pressure. Your accuracy is tracked per subject, so you always know whether Biochemistry is a strength to maintain or a weak area to drill.
Sample Biochemistry Questions
A newborn starts bleeding from the umbilical cord and nostrils a couple of days after delivery. This is due to deficiency of which vitamin?
- A.Vitamin D (deficiency causes rickets, not bleeding)
- B.Vitamin A (deficiency causes xerophthalmia and night blindness, not bleeding)
- C.Vitamin K
- D.Vitamin C (deficiency causes scurvy, which is rare in neonates)
A patient with hepatic failure is gradually developing hepatic encephalopathy. An increase in which compound is responsible for this deterioration?
- A.Creatinine (a marker of renal function, not this process)
- B.Urea (production is actually decreased, not increased, in liver failure)
- C.Glutamine
- D.Glutamate (an excitatory neurotransmitter, not the principal accumulating metabolite here)
A 15-year-old with type 1 diabetes mellitus has increased thirst, hunger, urination, and weight loss, with a fasting glucose of 400 mg/dL. What is the main reason he cannot maintain normal blood glucose?
- A.An abnormal response to glucagon (glucagon is not the primary defect)
- B.Decreased glucose output by the liver (hepatic output is actually increased in type 1 diabetes)
- C.A decreased glucagon-to-insulin ratio (this ratio is actually increased, a relative glucagon excess)
- D.Decreased uptake of glucose by peripheral cells
