The Doppler Effect is a crucial concept for the MCAT, particularly in the Chemistry & Physics section. We'll explore how the Doppler effect occurs when a wave source moves relative to an observer, affecting the observed frequency and wavelength. Using practical examples like an a ...  Show more

In this episode, we cover the topic of viruses. We explore a comprehensive range of subtopics including the definition and structure of viruses, their life cycles, and the differences between transduction and transfection. We also discuss virus classification, viral mutations, an ...  Show more

Differences in ion concentrations inside and outside a cell cause a difference in the charge of the intracellular and extracellular environments. This electrical polarization of a cell relative to its environment is referred to as cellular membrane potential. This potential se ...

In this episode, we’ll describe the human nervous system, focusing on its role in responding to environmental changes. We’ll talk about the system's key components: the brain, the spinal cord and the neurones. The entire system works together to protect the organism. We’ll ...

Ready to move beyond glycolysis? In Episode 26 of the Jack Westin MCAT Podcast, Mike and Molly guide you through the Pyruvate Dehydrogenase Complex (PDC) and the Citric Acid (TCA) Cycle—two of the highest‑yield pathways the MCAT loves to test.What we cover- Where it all happens – ...  Show more

In this episode, we will discuss ion deficiencies in plants.

Healthy plant development relies on mineral ions extracted from the soil. A lack of these ions, particularly magnesium and nitrates, leads to deficiency disorders.
