The MCAT Basics Podcast continues its series on Metabolism, and in today's episode, Alex Starks talks about the Krebs cycle, also known as the TCA cycle and Citric Acid cycle. This episode examines the chemistry, biochemistry, and biology of pyruvate metabolism and details how this high-yield MCAT topic will be tested on the AAMC MCAT Exam.   [01:30] Aerobic fate of Pyruvate [03:45] Acetyl-coa in the mitochondrial matrix [04:22] Visualizing the molecules and structure [06:10] The Krebs Cycle [23:56] ATP and The Electron Transport Chain [26:07] Quiz and Important Takeaways  Please email me if you have any comments or concerns: MCATpodcast@medschoolcoach.com To learn more about how MedSchoolCoach can help you along your medical school journey, visit us at Prospective Doctor.

The Krebs Cycle

Join us as we detail MCAT exam topics. Each podcast covers several MCAT sections with lessons based on review material put out by the AAMC, such as practice tests and question banks. Sam also interviews MCAT tutors and experts who share tips on how premed students can raise their score to get into medical school.

DNA replication and the central dogma are fundamental concepts in molecular biology, and breaking down the different replication methods and the processes of transcription and translation is crucial for understanding how genetic information is expressed and passed on in cells. In the first part of our episode, we'll break down DNA replication, exploring the concepts of conservative, semi-conservative, and dispersive replication, unraveling the mechanisms that drive this fundamental process. Later, we'll focus on transcription and translation, delving into the nuances between prokaryotic and eukaryotic organisms. We'll uncover the mechanisms by which genetic information is transcribed from DNA to RNA and then translated into proteins, all while considering the diverse cellular locations where these processes take place.

DNA Replication and Central Dogma

This podcast covers thermodynamics. First, I discuss the four laws of thermodynamics, as well as their application on the MCAT. Then, I break down enthalpy, Gibbs free energy, and entropy (briefly). Lastly, I cover the three types of heat transfer: conduction, convection, and radiation. CORRECTION: First Law of Thermodynamics is U =Q - W, I said 'U = Q + W'. For U = Q - W, W (work) is defined as work done BY the system on its surroundings.  Please email me if you have any comments or concerns: MCATpodcast@medschoolcoach.com To learn more about how MedSchoolCoach can help you along your medical school journey, visit us at Prospective Doctor.

This podcast covers cell and tissue types. First, I discuss the difference between eukaryotic and prokaryotic cells. I further break down these categories and talk about the differences between animal, plant, fungi, protozoa, archaea, and bacterial cells. Next, I talk about each of the four main tissue types: epithelial, muscle, connective, and nervous. The bulk of this section covers epithelial tissue.

Cell and Tissue Types

This podcast covers renal physiology. I start with a brief introduction to renal anatomy, then discuss in detail renal physiology. Next, I introduce three hormones (ADH, aldosterone, and ANP) that effect the kidneys and discuss their effects on the nephron. Lastly, I talk about measurements of renal function.

Renal Physiology

This podcast covers identity and psychosocial development. First, I will define a few terms you may see on the MCAT regarding identity. Next, I will breakdown the following theories of identity development: Erickson’s psychosocial development theory, Freud’s theory of psychosexual development, Paiget’s development theory, Kohlberg’s moral development theory, George Herbert Mead’s the I and the me, Cooley’s looking glass self, and Vygotsky’s social development theory.
