The main objectives of teaching biochemistry to undergraduate students are to help them comprehend the molecular foundation of life processes and to guide them toward using their newly learned knowledge to solve clinical issues. Biochemistry is among the pre-clinical subjects included in the first year of the MBBS curriculum. The subject is important in medical sciences as it provides a foundation for understanding the cellular and molecular basis of various physiological processes and disease mechanisms. The study of Biochemistry helps us understand cellular and molecular processes, the basis for molecular biology and genetics, enzyme and their metabolic pathway, drug development, and pharmacology, clinical diagnostics, Immunology and vaccine development, personalized medicine, nutritional sciences, and understanding the latest advancements.

It lays a groundwork for other medical disciplines and is integral to understanding the basis of health and diseases. Biochemistry subject holds great significance as it is a central science that connects various disciplines, providing valuable insights into molecular and chemical processes. It provides valuable insights into the molecular and chemical processes that govern life, making it an indispensable subject in modern scientific research ad application.

MBBS Prof Exam Pattern

From the 2019 batch onwards, the Biochemistry prof exam comprises two theory papers of 100 marks each and a practical examination of 100 marks. The theory exam consists of short answer questions, long answer questions, and application and case-based questions. The practical examination includes practical/clinical and viva.

Recommended books for Biochemistry include U. Satyanarayana & U. Chakrapani’s Biochemistry, Self-Assessment and Review of Biochemistry, Lippincott Illustrated Reviews: Biochemistry, and Harper’s Illustrated Biochemistry.

Subject Weightage in NEET-PG and INI-CET

The Biochemistry subject in NEET-PG carries a weightage of about 10-15 questions whereas the INI-CET exam carries a weightage of around 10 questions. The ideal way of preparing for the NEET-PG and other competitive examinations is to plan a preparation strategy that balances between low and high-weightage modules and subjects.
