#1. which one of the following statements correctly defines active site? the active site is a site on the enzyme molecule where specific substrate molecules bind./ the active site is a site on the substrate molecule where specific enzyme molecules bind./the active site is a site on the substrate molecule where specific product molecules bind. #2. why are enzymes known as biocatalysts?

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

just did the assignment and the answer was #1 +2 n
