Fat and Protein Metabolism
05/01/25 • 36 min
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. You'll get insights into the role of amino acids in synthesizing other compounds like serotonin and nucleotides.

Social Norms & Deviance
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 understanding.
