  • Newton’s Laws for the MCAT: Forces, Motion, and Acceleration Made Simple
    Oct 19 2026
    Newton’s three laws of motion are essential concepts for the Chemical and Physical Foundations section of the MCAT. In this episode of MCAT in the Car, we explain how forces affect movement, why mass and acceleration are connected, and how Newton’s laws apply to everyday situations and human physiology. You’ll learn the difference between balanced and unbalanced forces, understand the equation F equals m times a, and practice two MCAT-style questions without needing complicated calculations.

  • Enzyme Kinetics for the MCAT: Km, Vmax, and Competitive Inhibition Explained
    Oct 18 2026
    Enzyme kinetics is one of the most important biochemistry concepts tested on the MCAT. In this episode of MCAT in the Car, we explain how enzymes accelerate chemical reactions, what Km and Vmax tell us about enzyme activity, and how competitive and noncompetitive inhibitors change reaction rates. You’ll also learn how to recognize common MCAT questions about enzyme inhibition without getting lost in complicated equations.

  • Glycolysis for the MCAT: ATP, NADH, and the Three Enzymes You Must Know
    Oct 13 2026
    Glycolysis is one of the most important metabolic pathways tested on the MCAT, and understanding it is essential for mastering cellular energy production. In this episode, we break down how glucose is converted into pyruvate, why ATP is both consumed and produced, and how NADH contributes to cellular metabolism. You’ll learn the three key regulatory enzymes, the net ATP yield, and the differences between aerobic and anaerobic conditions. We also explore common MCAT exam traps involving enzyme regulation, energy calculations, and metabolic pathways, helping you recognize the concepts that frequently appear in passage-based questions.

  • Stoichiometry Made Simple: Moles, Limiting Reactants, and Chemical Reactions
    Oct 11 2026
    One of the most intimidating aspects of MCAT chemistry is stoichiometry. Students see chemical equations, unfamiliar numbers, and multiple conversion steps, and suddenly a relatively simple problem feels overwhelming. But stoichiometry is really about understanding proportions. Once you understand the relationships between substances in a chemical reaction, the calculations become much more manageable.

  • Lipid Digestion Explained: Enzymes, Micelles, and Chylomicrons
    Oct 8 2026
    Understanding lipid digestion requires connecting biochemistry with gastrointestinal physiology. This episode examines triglyceride hydrolysis, bile salt emulsification, micelle formation, and intestinal lipid transport. Discover how enterocytes reassemble triglycerides and package them into chylomicrons for transport through the lymphatic system. Review essential biochemical mechanisms and their clinical applications for the MCAT.

  • Atomic Structure and Periodic Trends: Why the Periodic Table Predicts Chemistry
    Oct 4 2026
    The periodic table is more than a collection of elements—it is a map that allows you to predict how atoms behave. In this episode of MCAT in the Car, we review atomic structure, electron configuration, valence electrons, and effective nuclear charge. You’ll learn the major periodic trends involving atomic radius, ionization energy, electron affinity, and electronegativity. More importantly, we’ll connect these trends so you can reason through MCAT questions rather than relying entirely on memorization. By the end, you should be able to look at an element’s position on the periodic table and make useful predictions about its chemical behavior.

  • The Optics & Waves Matrix: Mastering Lenses, Mirrors, Sound, and the Doppler Effect for the MCAT
    Sep 27 2026
    Optics and waves can become relatively easy MCAT points once you stop memorizing isolated equations and start recognizing predictable patterns. This study guide walks through converging and diverging lenses, mirrors, the thin-lens equation, sound waves, and the Doppler effect. Special attention is given to common MCAT traps and how Doppler ultrasound uses changes in frequency to determine blood velocity.

  • CRISPR Turns Down the Bradykinin Dial
    Sep 20 2026
    On September 8, 2026, the FDA accepted Intellia’s biologics application for lonvo-z, a one-time in vivo CRISPR therapy for hereditary angioedema, and gave it Priority Review. That matters because a single gene edit in the liver could replace lifelong attack-prevention drugs for a rare swelling disease driven by excess bradykinin. The core MCAT hook is how loss-of-function CRISPR editing of *KLKB1* lowers plasma kallikrein and slows a proteolytic cascade that opens vessels and floods tissue. The lesson and three practice questions reinforce CRISPR mechanics, enzyme cascades, capillary permeability, autosomal-dominant genetics, and how to read a randomized Phase 3 trial.
