Lab MCQs Mock Test Chapter 101 – Clinical Biochemistry
Test your knowledge of Clinical Biochemistry and Protein Biochemistry with Lab MCQs Mock Test – Chapter 101. This chapter contains 50 multiple-choice questions, covering MCQs 5001–5050, designed for Medical Laboratory Technicians, Medical Laboratory Scientists, Medical Laboratory Technologists, students, and candidates preparing for laboratory examinations.
The questions cover important topics related to amino acids, protein quality, protein nutrition, chemical score, biological value, and net protein utilization (NPU). You will also encounter questions about limiting amino acids in different food proteins, including rice, fish, pulses, eggs, milk, soybeans, and cereals.
This chapter also covers nutritional composition of milk and eggs, protein requirements, dietary protein, essential amino acids, conjugated proteins, albumin, globulins, and the albumin-to-globulin ratio.
Important protein chemistry concepts include protein structure, quaternary structure, isoelectric pH, zwitterions, disulfide bonds, hydrophilic amino acids, α-helix formation, cysteine-rich proteins, primary protein structure, electrostatic interactions, Sanger’s reagent, collagen, chaperonins, peptide bonds, and hydrogen bonding.
Read each question carefully, select the best answer, and complete the mock test to assess your Clinical Biochemistry knowledge and examination readiness.

Review Your Performance
After completing Lab MCQs Mock Test Chapter 101, review your score and identify the questions and topics that require further study.
Begin by reviewing protein nutrition and protein quality, including chemical score, biological value, net protein utilization (NPU), limiting amino acids, protein requirements, and the nutritional quality of different food proteins.
Pay particular attention to the amino-acid composition of common dietary proteins, including the limiting amino acids of rice, fish proteins, and pulses, as well as the nutritional characteristics of egg, milk, soybean, and cereal proteins.
You should also revise protein and nutritional composition of milk and eggs, including casein, vitellin, protein content, vitamin deficiencies, mineral deficiencies, and dietary protein requirements.
Another important area is plasma protein chemistry, including albumin, α1-globulin, γ-globulin, the albumin-to-globulin ratio, and the protein involved in the thymol turbidity test.
Finally, review the fundamental principles of protein structure and amino-acid chemistry, including isoelectric pH, zwitterions, disulfide bonds, hydrophilic side chains, α-helix formation, cysteine-rich proteins such as keratin, Sanger’s reagent, electrostatic interactions, collagen, protein-folding chaperones, peptide bonds, and hydrogen bonds.
Regular practice with Clinical Biochemistry MCQs can strengthen your understanding of protein chemistry, nutritional biochemistry, amino-acid properties, and laboratory concepts, while improving recall and examination confidence.
