The Doppler Effect
MCAT Basics (from MedSchoolCoach)
The Doppler Effect is a crucial concept for the MCAT, particularly in the Chemistry & Physics section. We'll explore how the Doppler effect occurs when a wave source moves relative to an observer, affecting the observed frequency and wavelength. Using practical examples like an ambulance speeding towards you, we'll bring these concepts to life. We'll also break down the Doppler effect equation, examining what it reveals—and what it doesn’t—about wave behavior. By the end of this episode, you'll have a solid understanding of The Doppler effect and will be ready to tackle any related...

Fat and Protein Metabolism
MCAT Basics (from MedSchoolCoach)
In this episode, we’ll nail down all that is needed for the MCATB in relation to fat and protein metabolism. Two critical processes for gaining energy and maintaining cellular functions in the body. We'll learn about the intricate details of beta-oxidation, where fatty acids are broken down in the mitochondrial matrix to produce energy-rich molecules like NADH, FADH2, and acetyl CoA. From protein catabolism, where proteins are broken down into amino acids that feed into gluconeogenesis and ketosis pathways, to protein anabolism, where these amino acids are incorporated into new proteins....

Social Norms & Deviance
MCAT Basics (from MedSchoolCoach)
Social norms and deviance as covered in the MCAT is a fascinating topic, and in this episode, we'll break down the intersection of social norms—folkways, mores, taboos, and laws—how they play a crucial role in shaping societal values, and what happens when these norms break down, a concept known as anomy. Plus, we'll delve into collective behavior phenomena such as fads, mass hysteria, moral panic, and riots, touching on some real-life examples and historical comparisons. Expect a comprehensive overview, with real-world relevance and plenty of examples to help solidify your...

Population Genetics
MCAT Basics (from MedSchoolCoach)
In this episode, we discuss population genetics and see how genetically related individuals share the same alleles, delving into the mechanisms of gene flow and genetic drift. We'll also unravel the complexities of hybrid vigor, reproductive isolation, and natural selection, and how these processes shape the genetic landscape of populations. We'll also touch on the fascinating dynamics of X-linked and mitochondrial inheritance, and the role of genomic imprinting in disease risk. Ever wondered how the Hardy-Weinberg equation helps us understand genetic equilibrium in populations?...

Common Hormone Axes
MCAT Basics (from MedSchoolCoach)
In this episode, we'll explore three crucial hormone axes: the hypothalamic-pituitary-adrenal (HPA) axis, the hypothalamic-pituitary-gonadal (HPG) axis, and the renin-angiotensin-aldosterone (RAAS) system. We'll decode the complex interplays among the hypothalamus, pituitary gland, and various peripheral organs, focusing on how these hormone systems regulate everything from stress responses and reproductive functions to blood pressure and fluid balance. We'll break down the HPA axis and its pivotal role in stress response, featuring hormones like corticotropin-releasing hormone (CRH) and...
info_outlineRedox 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.
