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. Visit MedSchoolCoach.com for more help with the MCAT.
