Tackle High-Yield Concepts for USMLE Step 2 CK Cardiology

This interactive session, led by Dr. Abraham Titus (Hematology/Oncology Fellow, University of South Alabama) and Schola ...

This MCAT Basics podcast covers biological membranes. First, the podcast introduces a few topics regarding membranes: what they are, how they are formed, their presence in the cell, and cell-to-cell junctions. Second, it addresses transport through the membrane, including simp ...

In this episode, we look at transportation in cells. We will explain how substances move into and out of cells, highlighting three key mechanisms. Diffusion is described as the movement of particles from high to low concentration areas. Osmosis is presented as a specific type of ...  Show more

In this episode of MCAT Basics, we’ll cover Electrochemistry. We start with the role of salt bridges in electrochemical cells and cover the intricacies of cell notation. We’ll also discuss how ions maintain charge balance, the importance of reduction and oxidation potentials, ...

In this episode, we focus on biosignaling and cover how cells communicate through systems like voltage-gated and ligand-gated ion channels, using real-world examples such as neuronal signaling and muscle contraction. We also break down the role of enzyme-linked receptors, specifi ...  Show more
