Mastering Key components for MCAT

Updated: Jan 14

MCAT Medical college Admission Test consist of 7 essential key Components that include. The seven key units in the SKI MCAT plan typically correspond to the four MCAT sections, with additional emphasis on specific skills. Here's a breakdown:

  1. Biological and Biochemical Foundations of Living Systems (Section I):

  • Biochemistry

  • Biology

  • Organic Chemistry

  1. Chemical and Physical Foundations of Biological Systems (Section II):

  • Physics

  • General Chemistry

  • Organic Chemistry

  1. Psychological, Social, and Biological Foundations of Behavior (Section III):

  • Psychology

  • Sociology

  1. Critical Analysis and Reasoning Skills (CARS) (Section IV):

  • Reading Comprehension

  • Critical Thinking

Mastering biochemistry is crucial for success in the MCAT, particularly in the Biological and Biochemical Foundations of Living Systems section. Here are seven tips to help you excel in MCAT biochemistry: 

Understand Key Concepts: 

  • Develop a strong foundation in fundamental biochemistry concepts such as enzyme kinetics, metabolism, cell structure, and molecular biology. 

  • Pay attention to important molecules, pathways, and biochemical reactions. 

  • Biochemistry is often interdisciplinary, so integrate your understanding of biology and chemistry. Recognize how biochemical principles apply to cellular processes and physiology. 

  • Connect biochemistry concepts with other MCAT sections, as questions may test your ability to synthesize information. 

  • Amino acids and proteins are fundamental to biochemistry. Memorize the structures, properties, and functions of amino acids. Understand protein structure (primary, secondary, tertiary, quaternary) and how it relates to function. With the help of detailed course study by SKI MCAT Aspiring Physicians, you can: Memorize: Learn the structures, abbreviations, one-letter and three-letter codes, and classifications (polar, nonpolar, acidic, basic) of amino acids.         Functions: Understand the role of amino acids in protein structure, enzymatic activity, and signaling pathways. Protein Structure: Grasp the different levels of protein structure, including primary, secondary (alpha helix, beta-sheet), tertiary, and quaternary structures. Enzyme Function: Understand enzyme catalysis, substrate specificity, and the concept of active sites. Enzyme Kinetics: Learn about Michaelis-Menten kinetics, Lineweaver-Burk plots, and factors affecting enzyme activity (temperature, pH, inhibitors). 

Master Metabolic Pathways with variety of MCAT resources in Aspiring Physicians program: 

  • Memorize key metabolic pathways such as glycolysis, gluconeogenesis, the citric acid cycle, and oxidative phosphorylation. Glycolysis and Gluconeogenesis: Memorize the key intermediates, enzymes, and regulation of these pathways. Citric Acid Cycle (Krebs Cycle): Understand the steps, products, and regulation of this central metabolic pathway. Oxidative Phosphorylation: Learn about electron transport chain, ATP synthesis, and the role of oxygen. 

  • Understand the regulation of these pathways and how they interconnect. 

  • Utilize official AAMC practice materials and SKI resources to practice biochemistry questions. 

  • Familiarize yourself with the way biochemistry concepts are tested on the MCAT, and practice interpreting experimental data. Experimental Techniques: Understand common biochemical laboratory techniques, such as gel electrophoresis, chromatography, and polymerase chain reaction (PCR). Interpretation of Data: Practice interpreting experimental data and graphs related to biochemical experiments. 


  • Biochemistry involves memorizing numerous structures, pathways, and interactions. Use mnemonics, diagrams, and visual aids to enhance memory retention present in the lecture videos. 

  • Create concept maps or flowcharts to represent biochemical processes and their regulation. 

Stay Updated with Recent Research: 

  • Biochemistry is a dynamic field with ongoing research. While the MCAT tests fundamental concepts, staying informed about recent discoveries can deepen your understanding. 

  • Follow SKI reputable sources and scientific journals to stay updated on advancements in biochemistry.   

  • Join our groups on Facebook and WhatsApp to get updated on recent news about MCAT. 

Additional Tips: 

  • Active Learning: Engage in active learning through flashcards, concept maps, and teaching concepts to others. 

  • Practice Questions: Utilize SKI MCAT-style practice questions and exams to test your understanding and identify areas for improvement. 

  • Review Weak Areas: Regularly assess your progress and dedicate more time to areas where you struggle. 


Remember to incorporate biochemistry into your overall study plan and allocate sufficient time to this section. Consistent practice and a comprehensive understanding of key concepts will contribute to your success in the MCAT Biochemistry section.
