The Cell Cycle show art The Cell Cycle

MCAT Basics (from MedSchoolCoach)

In this episode, we explore the different phases of the cell cycle: Interphase (G1, S, G2) and the M phase (mitosis). Next, we discuss the regulation of the cell cycle and the key checkpoints that ensure its proper progression. Finally, we touch on how dysfunction in the cell cycle can lead to diseases, particularly cancer. This material is likely to appear in the Bio/Biochem section of the MCAT.   Visit for more help with the MCAT.   [00:00] Introduction [02:06] Overview of the cell cycle [02:38] Two main phases of the cell cycle [04:11] Interphase  [12:43] Mitotic phase...

Emotion and Motivation show art Emotion and Motivation

MCAT Basics (from MedSchoolCoach)

In this episode, we cover motivation and emotion–key concepts that will show up in the Psychological, Social, and Biological Foundations of Behavior section of the MCAT. We start with the difference between intrinsic and extrinsic motivation. We then go into various theories including evolutionary, arousal, drive-reduction, incentive, three needs theory, Maslow’s hierarchy, and the correlation between harmful behaviors like addiction and motivation.  Lastly we get into emotion, covering its three components, the relationship between emotion and the brain, and an array of theories...

Cardiovascular System + Fluids show art Cardiovascular System + Fluids

MCAT Basics (from MedSchoolCoach)

In this episode, we focus on the cardiovascular system and its connection to fluid mechanics. Beginning with an exploration of cardiovascular anatomy, the discussion covers various aspects of the heart: its function, contraction mechanism, the diverse cell types found within it, and its essential role in regulating blood pressure.  Finally, in the latter part of the episode, several fluid mechanics topics pertinent to the MCAT and their application to the cardiovascular system are addressed. These include total peripheral resistance, viscosity, the continuity equation, and the Bernoulli...

Adaptive Immune System show art Adaptive Immune System

MCAT Basics (from MedSchoolCoach)

To continue our discussion on the immune system, in this episode, we will cover the second type of immune system – the adaptive immune system.    We start with covering some vocabulary that you’ll need to know to understand the immune system, then we move into the cells that make up the adaptive immune system. Then we break down the two branches of the adaptive immune system -  humoral immunity including the discussion of B cells and cell-mediated immunity highlighting T cells.   Don’t miss our previous episode on the other type of immune system, the innate...

More Episodes

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.
