Enzyme + Substrate ES complex Enzyme + Products
bond two substrates into one product
Which is the enzyme?
Which is the substrate?
What is the other reagent then?!?
What are the products of this reaction?

Guiacol turns brown when oxidized. (and it gets more and more brown as more of the guiacol is oxidized).
With a spectrophotometer!
Tannic acid is used to form a scab on a burn. An egg becomes hard boiled when placed in hot water. What is similar about these two events?
Acid and heat cause a denaturation of protein. They both break bonds in the structure of protein.
If the temperature gets too high, the enzyme may be denatured!
