(B1.1) - Carbohydrates [In A Nutshell] - IB Biology (SL/HL)

Our Website | teachmebio.org They’re not just pasta—although, let’s be real, pasta is amazing. Carbs are your body’s favorite snack, its primary fuel source, and honestly? A structural flex. Unwrap the surprisingly juicy (and slightly sticky) science of carbohydrates for IB Biology. No more crying over your textbook. In this video, we’ll make it painfully clear—in a fun way: Glucose structure – spoiler: it looks like a molecular mood ring. Glycogen vs. starch vs. cellulose – one is your energy backup, one is french fry fuel, and one is basically plant armor. Guess which one you can’t digest (hint: don’t eat the tree). Why cellulose is the ultimate plant superhero – it’s strong, it’s fibrous, and it’s the reason salads don’t instantly collapse into sad green goo. Stop cramming like a desperate squirrel. Start understanding the energy of life—with 70% less confusion and 100% more bad carb-related puns.
