STS Biology Review Pod

Episode 1.3: Intro to Macromolecules In this episode of the STS Biology Review Pod, Schuyler and Leslie dive into the "molecules of life" that make all living things possible. Whether you're prepping for AP Bio or just curious about how our bodies work, this episode breaks down the four major classes of macromolecules: carbohydrates, lipids, proteins, and nucleic acids. We cover: What macromolecul...

Welcome back to the STS Biology Review Pod! In Episode 3, hosts Schuyler and Leslie dive deep into the fundamental chemistry powering all living things: acids, bases, and the mysterious world of pH. Building on last week's exploration of life's essential elements, this episode breaks down what happens when substances dissolve in water, transforming into charged ions that drive nerve signaling, dig...

In this episode, we study the essential elements that form the foundation of all living things. We'll introduce the "Big Four" elements—carbon, hydrogen, oxygen, and nitrogen—and break down how each one is crucial to core biological molecules and processes. [memorization acronym for big four: CHON] You'll learn how carbon's versatility makes complex life possible, why hydrogen and oxygen are key f...

We review subatomic particles like protons, neutrons, and electrons. After, we discuss the nature of water's polarity, including covalent bonding and other types. Additionally, we consider specific heat capacity, heat of vaporation, expansion with freezing, ability to be a solvent, and cohesion.
