http://chemistry.elmhurst.edu/vchembook/570enzymes.html WebEnzymes are often named for the substrates on which they act. Thus, the enzymes involved in the reactions above would be sucrase and lactase respectively. Notice that the suffix –ase is added to the name of the substrate. An enzyme’s shape governs its function. Each enzyme has an active site where only certain molecules (substrates) can bind.

Because enzymes are not part of the product, they can be reused again and again. How efficient! This is an example of an enzyme molecule (blue) and a substrate (yellow). The enzyme and substrate fit together like a lock and key to make the product. WebThe lock-and-key model assumed that both the enzyme and the substrate were rigid structures, with the substrate fitting precisely into the active site, just as a key fits into a lock. The observation of enzyme activity in reactions supported this theory and led to the conclusion that enzymes are specific to the reaction they catalyse. eastside investment club olympia
