Watch It Move: Enzyme Lock-and-Key
A “Watch it move” animation for Biology Made Fun, Unit 3 — the code printed on page 31, Unit 3's Color & Label enzyme page.
Animation — Enzyme Lock-and-KeyThe concept animation for this page will be embedded here.
Key ideas from the lesson
- A substrate fits into the enzyme's active site like a key into a lock — the shape match is the whole mechanism.
- The enzyme changes the substrate and releases the products; the enzyme itself comes out unchanged and can work again.
- If the enzyme loses its shape — denatured — the key no longer fits and the reaction stops being helped.
Why this helps
This is the “Watch it move” companion to Unit 3's Color & Label enzyme page: the drawing you colored, running as the process it describes.
Try this
Watch once for the fit and once for the exit: what enters the active site, what leaves it, and what is exactly the same at the end as at the start?
