Unit 3.1 - Enzymes
LECTURE VIDEO
DESCRIPTION
They’re the tiny, over-caffeinated workers that run your entire body 24/7. They’re biological matchmakers, molecular Pac-Men, and the reason your lunch doesn’t just sit in your stomach forever.
They are ENZYMES. In this video, we’ll make sure you conquer:
- The “Lock and Key” & “Induced Fit” Model: Is an enzyme a rigid lock or an enthusiastic, squishy handshake? (Spoiler: It’s weirder than you think).
- Activation Energy: The bouncer at the club of every chemical reaction, and how enzymes basically fire the bouncer and let everyone in for free.
- Difference between intracellular and extracellular enzymes (and why Po needs them)
Forget boring textbooks. We’re diving into the frantic, microscopic factory inside you. Master the content, ace your exam, and finally understand why your teacher keeps drawing weird pac-men. It’s time to catalyze your learning!

Unit 3.2 - Environmental Impacts On Enzyme Function
LECTURE VIDEO
DESCRIPTION
They’re not just fussy proteins (that throw a fit if the pH is wrong)—they’re the *frantic matchmakers* of every chemical reaction in your body. Dive into the high-maintenance world of enzymes for AP Biology.
This video turns up the heat (but not too much!) to explain:
- Temperature Tantrums: Why a little heat speeds them up, but too much turns them into a permanently scrambled egg.
- The pH Panic: Discover why some enzymes are drama queens that only work in a specific acidity zone.
- Enzyme Concentration: What happens when the matchmakers outnumber the singles?
- Substrate Showdowns: We graph what happens when a party gets too crowded.
- Inhibitors – The Party Crashers: Meet the competitive bullies and the non-competitive saboteurs who ruin the fun for everyone.
Understand the diva molecules that make your metabolism possible, one perfectly-catalyzed tantrum at a time.

Unit 3.3 - Cellular Energy
LECTURE VIDEO
DESCRIPTION
In this video us BIG BRAINS will talk about the different aspects of noodle salads in order to substantially expand our understanding of jelly beans and puppy paws. Not only that, we will also be identifying structures we have never seen before such as feather soil, wand oil and of course: peanut nanocarbons and puffskittles.
