WebJul 26, 2024 · Figure 7.1.1. 1: Enzymesare substances present in the cell in small amounts which speed up or catalyze chemical reactions. Enzymes speed up the rate of chemical reactions because they lower the energy of activation, the energy that must be supplied in order for molecules to react with one another. Enzymes lower the energy of activation by ... WebDiscuss enzyme regulation by various factors. A substance that helps a chemical reaction to occur is a catalyst, and the special molecules that catalyze biochemical reactions are enzymes. Almost all enzymes are proteins, comprised of amino acid chains, and they perform the critical task of lowering the activation energies of chemical reactions ...

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. WebEnzymes are proteins that function as biological catalysts. So, they are molecules that speed up a chemical reaction without being changed by the reaction. Lock and key hypothesis Enzymes...
