In this episode, we cover the topic of work and energy. We’ll start off by talking about work, which includes the mathematical and conceptual definitions and the sign convention of work. We’ll also talk a little bit about mechanical advantage and also path dependency. Moving on to energy, we’ll talk about the general definition of energy, we’ll compare and contrast energy in work and the different types of energy that includes kinetic energy, potential energy, thermal energy, and total mechanical energy. Lastly, we’ll talk about energy transfer, specifically heat transfer, and the three types of convection, conduction, and radiation.

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 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.
