WebWhen substrates are added to the medium, they bind to the active sites present on the enzyme based on their specificity using non-covalent interactions. This binding on the enzyme with the substrates forms an intermediate complex known as the Enzyme-substrate complex. The substrates are broken down into the products at the active site. WebOct 4, 2024 · 6.2: Enzyme Binding. The lock-and-key model of enzymes says that enzymes bind specific molecules and carry out reactions on those molecules. The enzyme recognizes the shape of its substrate and it is able to hold it in position in what is called the active site. The active site is the part of the enzyme that binds the substrate and carries out ...

WebEnzymes function to reduce the activation energy required for a chemical reaction to occur. First, the enzyme binds to the substrate and slightly distorts its shape. The change in shape activates the substrate molecule and decreases the total activation energy required for the substrate to be turned into product. WebThe process of an enzyme at work: Step-1 : An enzyme and a substrate are in the same area. The substrate is the biological molecule that the enzymes will work on. Step-2 : A special …
