Enzyme reaction

How does an enzyme turn one long chain into smaller molecules?

Follow a starch chain into amylase and watch one bond break, one step at a time.

Look closer.

  1. Follow substrate binding, hydrolysis and product release.
  2. Explore the active site and why the enzyme can act again.
  3. Use the A-level view to investigate induced fit.
