How Biochemistry is asked in exams

Biochemistry for pharmacy is lighter than medical biochemistry. Exam questions mostly ask about vitamin deficiency diseases, normal laboratory values, enzymes and the main steps of glucose metabolism. Students usually lose marks on normal values, because they read them once and never revise. A small chart of numbers fixes this problem in a single evening.

Biochemistry MCQ for Pharmacy mistakes students make, and the logic behind them

These are the questions from the set above that students most often get wrong, with the reason behind each answer.

What is the net ATP gain from glycolysis of one glucose molecule?
Answer: 2 ATP. Four ATP are produced, but two are used in the early steps, so the net gain is two.
What is the end product of anaerobic glycolysis in muscle?
Answer: Lactate. Pyruvate is converted to lactate so that NAD+ is regenerated and glycolysis can continue.
Match the deficiency: scurvy, pellagra, beriberi and pernicious anaemia.
Answer: Vitamin C, niacin, thiamine and vitamin B12 respectively. These four are among the most repeated one-line questions in vitamin chapters.
What does HbA1c reflect?
Answer: Average blood glucose over the past 2 to 3 months. A normal random glucose test shows only the level at that moment.
Vitamin K is required for the synthesis of which factors?
Answer: Clotting factors II, VII, IX and X. This is also why warfarin, which blocks vitamin K recycling, prolongs clotting time.

Quick revision points for Biochemistry

Glycolysis takes place in the cytoplasm, and the Krebs cycle in the mitochondrial matrix.
Normal fasting blood glucose is about 70 to 100 mg/dL, and normal blood pH is 7.35 to 7.45.
Haemoglobin in adult men is about 13 to 17 g/dL, WBC count is 4000 to 11000 per cu mm and platelets are 1.5 to 4 lakh per cu mm.
Raised SGPT (ALT) points to liver disease, raised troponin to myocardial infarction and raised creatinine to kidney problems.
Bilirubin accumulates in jaundice, and LDL cholesterol is called bad cholesterol.
Haemoglobin contains iron, and vitamin B12 contains cobalt.

A simple way to learn from your mistakes

Write the normal values on a single card and keep it in your pocket. Read it three times a day for a week. Then attempt this biochemistry MCQ for pharmacy quiz again. Most students find that the lab-value questions become the easiest ones after this small habit.

Frequently asked questions about biochemistry MCQ for pharmacy

Is biochemistry important for pharmacy exams?

Yes, it supports pharmacology, clinical pharmacy and pathology. Vitamins, enzymes and lab values are asked in most pharmacist exams.

Which vitamins should I focus on?

Learn the fat-soluble vitamins (A, D, E, K) and the deficiency diseases of vitamin C and the B-complex first.

Does this quiz include lab values?

Yes. It covers glucose, haemoglobin, WBC, platelets and common enzyme and cardiac markers.
