Metabolism

Or, Anna's Tower and Its Untimely Destruction.

You'll remember the difference between Anabolism and Catabolism with this playful science mnemonic.

No cats were injured during the making of this video.

Commemorates 2000 views of "My Benzene Ring." Thank you!

When you see Anabolic think Anna builds with blocks. An anabolic process takes small molecules, or monomers, and adds them together into a macromolecule or polymer. This is a lot like our friend Anna here, taking blocks and making a tower.

So, sugars become polysaccharides, amino acids become polypeptides (which then fold into proteins), and nucleotides become nucleic acids (DNA or RNA).

Youll probably get an extra point if you remember that the process is called dehydration synthesis, because when the monomers covalently bond together, it releases water. But, if you can just remember that Anna builds towers out of blocks, youll be on your way.

When you see Catabolic, think Cat breaks down block towers. A catabolic process takes large molecules or polymers and breaks them back down into the small. Hydrolysis (or cutting bonds with water) is the opposite of dehydration synthesis.
