MCAT Basics (from MedSchoolCoach)

Redox reactions or reduction and oxidation are reactions in which electrons are simultaneously transferred from one chemical species to another. This episode begins with exploring this concept, including an in-depth look at oxidizing and reducing agents and the factors determining a compound's effectiveness as an oxidizing agent. 
It also covers the oxidation states of molecules and functional groups, common redox reagents in organic chemistry, and the role of redox in biological systems. The episode also addresses numerical concepts from general chemistry related to redox, such as determining oxidation numbers and understanding electrochemical cells.

In this episode, we explore the topic of intelligence, which is primarily featured in the psychology and sociology section of the MCAT.
We cover several key theories, including entity vs. incremental theory, general intelligence theory, two-factor theory, multiple intelligences theory, Triarchic theory, CHC theory, and biological theories. Additionally, we examine the nature vs. nurture debate on hereditary intelligence factors and discuss how intelligence is measured.

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.

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.

The immune system is split up into two main categories - the adaptive immune system and the innate immune system. 
This episode will cover the intricacies of the innate immune system beginning with an overview of its constituent cells. We will then explore three pivotal elements of the system: anatomical barriers, the general inflammatory response, and the complement system. This will show up in the bio/biochem section of the MCAT.
For additional reading on this topic, you can refer to the NIH’s Innate Immune System paper.
