MCAT Basics (from MedSchoolCoach‪)‬ MedSchoolCoach

This episode of MCAT Basics covers several separation and purification techniques you may see on the MCAT. We’ll cover these techniques in three distinct categories: small molecules, proteins, and cells. 
Within the small molecule category, we’ll discuss extraction, crystallization and recrystallization, and chromatography (TLC and HPLC).
For proteins, we cover SDS-page, precipitation, soelectric focusing, and chromatography variations. Lastly, we’ll explain, within the world of cells, centrifugation, flow cytometry, and microfluidics.

This episode of MCAT Basics covers the world of circuits. We will explore electrical circuits and their fundamental principles.
We’ll start with dissecting the essential parameters that form the backbone of circuits: voltage, current, resistance, and power. These are the building blocks upon which all circuit dynamics are based.
Next, we'll explore a variety of circuit elements, from resistors to batteries, capacitors, and switches. Each of these components plays a vital role in shaping the behavior of circuits and understanding their functionality.
Finally, we'll delve into Ohm’s Law and Kirchhoff’s Law, two fundamental principles that govern circuit behavior. By grasping these laws, you'll gain essential insights into how circuits operate and how to analyze their dynamics effectively.

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.

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.

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.

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.
