    Electrochemistry

    Electrochemistry

    In this episode of MCAT Basics, we’ll cover Electrochemistry. We start with the role of salt bridges in electrochemical cells and cover the intricacies of cell notation. We’ll also discuss how ions maintain charge balance, the importance of reduction and oxidation potentials, and how these elements come together in galvanic and electrolytic cells. We’ll also take a closer look at concentration cells and the critical Nernst equation, which helps us understand cell potentials under non-standard conditions.

    Biological Membranes

    Biological Membranes

    This MCAT Basics podcast covers biological membranes. First, the podcast introduces a few topics regarding membranes: what they are, how they are formed, their presence in the cell, and cell-to-cell junctions. Second, it addresses transport through the membrane, including simple diffusion, active vs. passive transport, and transport membrane proteins. Next, the discussion moves to membrane proteins, including receptors, transporters, and the differences between integral, peripheral, and lipid-anchored proteins. Finally, the podcast covers membrane dynamics, such as endocytosis and the transmembrane system, and discusses membrane potential.

    Adenosine Triphosphate or ATP

    Adenosine Triphosphate or ATP

    In this episode, we’ll talk about  ATP or adenosine triphosphate. We will begin with a detailed examination of ATP's structure and composition as a nucleotide, followed by an explanation of the metabolic pathways involved in its production—both aerobic and anaerobic. We will also cover the pivotal process of ATP hydrolysis, emphasizing its energy release and crucial role in various cellular processes, including the sodium-potassium pump and protein phosphorylation.
    Additionally, we will address the limitations of ATP supplementation and the broader implications of ATP in biological transport and biosynthesis processes. This episode promises to provide a clear and thorough understanding of ATP's essential functions, ensuring you are well-prepared for your MCAT studies.

    Intelligence

    Intelligence

    In this episode, we explore the topic of intelligence, which is primarily featured in the psychology and sociology section of the MCAT.
    We cover several key theories, including entity vs. incremental theory, general intelligence theory, two-factor theory, multiple intelligences theory, Triarchic theory, CHC theory, and biological theories. Additionally, we examine the nature vs. nurture debate on hereditary intelligence factors and discuss how intelligence is measured.

    Redox Reactions: Reduction and Oxidation

    Redox Reactions: Reduction and Oxidation

    Redox reactions or reduction and oxidation are reactions in which electrons are simultaneously transferred from one chemical species to another. This episode begins with exploring this concept, including an in-depth look at oxidizing and reducing agents and the factors determining a compound's effectiveness as an oxidizing agent. 
    It also covers the oxidation states of molecules and functional groups, common redox reagents in organic chemistry, and the role of redox in biological systems. The episode also addresses numerical concepts from general chemistry related to redox, such as determining oxidation numbers and understanding electrochemical cells.

    [00:00] Introduction
    [01:09] What is the conceptual definition of redox
    [06:22] What is an oxidizing agent, and what is a reducing agent?
    [08:50] What makes a molecule better than another at being an oxidizing agent or a reducing agent?
    [13:58] Which oxidation reduction reagents should you know and what do they
    [21:44] Redox in biological systems
    [35:01] How to determine the oxidation state

Love the show

Love the show, but i miss the old intro. I understand that you’re wanting to plug medschoolcoach, but that intro doesn’t have that warm feeling anymore. Sam, i appreciate the content and i never miss an episode.

Super clutch !!!!

This podcast is so amazing. One of the most helpful resources to supplement my content review but also adds in additional details I may have missed. Easiest way to reinforce concepts while driving and it also helps mix up types of studying to prevent burnout :,)

Helpful!

This was perfect for commutes. He explains everything clearly and also adds some humor and interesting facts. I listened to this podcast almost every time I was in the car for the past few months. Thank you!
