MCAT Biochemistry concepts

Here are frequently tested core topics in the biochemistry section of the MCAT:

Amino Acids and Protein Structure:

A strong understanding of amino acids is fundamental as they are the building blocks of proteins. Familiarize yourself with the 20 common amino acids, their properties, and their classifications. Additionally, learn about the different levels of protein structure, including primary, secondary, tertiary, and quaternary structures.

Enzymes and Enzyme Kinetics:

Enzymes are biological catalysts that play a vital role in biochemical reactions. Focus on enzyme kinetics, including factors affecting enzymatic activity, such as temperature, pH, and substrate concentration. Understand concepts like Michaelis-Menten kinetics, enzyme inhibition, and enzyme regulation.


Metabolism encompasses the chemical reactions that occur within living organisms. Familiarize yourself with the pathways involved in catabolism (breaking down molecules) and anabolism (building molecules). Key pathways to focus on include glycolysis, the citric acid cycle, oxidative phosphorylation, and gluconeogenesis.

Carbohydrate, Lipid, and Nucleic Acid Metabolism:

Dive deeper into the metabolism of carbohydrates, lipids, and nucleic acids. Understand how these macromolecules are synthesized, broken down, and utilized by the body. Pay special attention to essential concepts like glycolysis, fatty acid synthesis and oxidation, and DNA replication.

Biochemical Techniques:

Develop a working knowledge of common biochemical techniques used in research and diagnostics. These techniques may include chromatography, electrophoresis, spectroscopy, and DNA sequencing. Understanding these techniques will enable you to interpret experimental data and solve related MCAT questions.

To succeed in MCAT Biochemistry, here are some strategies you can employ:

1. Start Early and Plan Your Study Schedule

Begin studying about three to six months before your MCAT test date, depending on how many hours you can devote to studying daily. This gives you enough time to learn the information but doesn’t leave you with so much extra time that you begin to forget the information. Plan your study schedule in advance, allocating dedicated time for Bio/Biochem.

3. Practice with MCAT Practice Tests

Once you’ve begun reviewing and studying biology and biochemistry, incorporate MCAT practice tests into your routine. Third-party practice tests are great during the initial stages of studying. As you approach your test date, prioritize taking the AAMC practice tests. These tests closely resemble the actual exam, so complete every AAMC practice test available.

4. Incorporate Regular Bio/Biochem Practice Questions

In addition to practice tests, integrate regular practice questions focused on Bio/Biochem into your study sessions. Utilize test preparation techniques like spaced repetition and periodic reinforcement to ensure the retention of high-yield topics, such as amino acids. Regularly revisiting these topics will help reinforce your understanding and retention.

5. Enhance Critical Thinking Skills

Because the Bio/Biochem section tests your ability to think critically about information, it’s imperative to take your preparation beyond mere factual knowledge. Practice analyzing and manipulating information through practice tests. The more you engage in critical thinking exercises, the better you’ll be able to demonstrate your skills on test day.

6. Identify and Prioritize Weak Areas

As you progress in your studies, you’ll identify your strengths and weaknesses. Adjust your study time accordingly, devoting more or less time to Bio/Biochem based on your needs. This approach ensures efficient use of your study time and prevents unnecessary review of mastered information.

7. Strengthen Active Reading and Graph Interpretation

In addition to learning the content, focus on enhancing your skills in two critical areas: active reading and interpreting graphs, figures, and tables. Active reading involves engaging with passages, highlighting key information, taking notes, summarizing content, and organizing information effectively. 

Similarly, practice interpreting graphs, figures, and tables, identifying essential elements such as titles, axes, independent and dependent variables, and patterns. Regular practice of these skills will enable you to comprehend and analyze information during the exam swiftly.

Summing Up

In a nutshell, mastering MCAT Biochemistry is vital for your exam success. Start early, understand the facts, and apply your knowledge. Practice with tests and questions focused on Biochemistry. Improve critical thinking by analyzing and manipulating information. Adjust your study time based on your strengths and weaknesses. 

Enhance active reading and graph interpretation skills. Consider getting expert help from Medic Mind’s 1-1 tutoring program for personalized guidance and study materials. By following these strategies, you’ll be well-prepared to excel in the MCAT Biochemistry section and achieve your goals.


How much time should I dedicate to studying MCAT Biochemistry?

The recommended study time for MCAT Biochemistry varies, but generally, three to six months of focused preparation is ideal. Dedicate enough hours per day based on your schedule, ensuring sufficient time to learn and retain the information without overwhelming yourself.

How can I improve my critical thinking skills for the MCAT Biochemistry section?

Engage in regular practice tests and questions that require critical thinking and application of knowledge. Analyze the reasoning behind each answer choice and understand why certain options are correct or incorrect. Focus on identifying key patterns, connecting, and applying conceptual understanding to different scenarios.

How can I balance studying for MCAT Biochemistry with other sections of the exam?

Initially, allocate equal time to all four sections of the MCAT. As you progress, adjust your study time based on your strengths and weaknesses. Devote more time to Biochemistry if needed, ensuring efficient use of your study hours and avoiding the unnecessary review of mastered concepts.

What should I do if I find MCAT Biochemistry overwhelming?

Break down the topics into smaller, manageable portions, focusing on one concept at a time. Seek clarification from tutors, join study groups, or utilize online forums to discuss challenging areas. Practice regularly and gradually build your understanding and confidence in tackling biochemistry questions.

Can I succeed in MCAT Biochemistry if I haven’t taken an extensive biochemistry course in college?

Yes, you can still succeed in MCAT Biochemistry even without an extensive college course. The MCAT is designed to test your understanding and application of fundamental biochemistry
