#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?
Active sites in enzymes are where substrates bind. Once they bind, a catalytic reaction occurs as a complex between substrate and enzyme is formed. Enzymes are termed as biocatalysts or simply catalysts since they speed up the catalytic reaction. After the reaction, they simply revert back to their original form, after having adjusted to fit with substrate.
