Describe an active site
Did you know?
The active site of an enzyme is the region that binds substrate molecules. This is crucial for the enzyme’s catalytic activity. Enzymes are proteins that drastically increase the speed of chemical reactions by lowering their activation energy. They do this by interacting with chemical reactants – the substrates – in … See more Because enzymes – like all proteins – are made of amino acids, there are a wide variety of potential sequences. Therefore, their active sites also … See more There are two theories about how exactly an enzyme active site binds to substrates. These are the lock and key model and the induced fit model. See more Some examples of chemical reactions catalyzed by enzymes include the breakdown of starch by maltase, the breakdown of proteins by pepsin, and the synthesis of DNA by DNA polymerase. For each of these … See more WebIn contrast, allosteric inhibitors bind to regions of the protein away from the active site, but change the shape of the active site such that substrate cannot bind. Since there is no direct competition, increasing substrate concentration cannot overcome allosteric inhibition. Non-competitive inhibition is a type of allosteric inhibition.
