Enzymes are catalysts that drive reaction rates forward. Most catalysts, but not all, are made up of amino acid chains called proteins that accelerate the rate of reactions in chemical systems. The functionality of a catalyst depends on how the proteins are folded, what they bind to, and what they react with.
WebEnzymes are subjected to regulation, to adapt to the requirements of different cells. This regulation can occur by changes in S concentration, covalent modifications (phosphorylation), and by allosteric factors that bind to a place in the E different to the active site. Isozymes are different proteins that have the same enzyme activity.
WebMay 28, 2024 · An enzyme is defined as a macromolecule that catalyzes a biochemical reaction. In this type of chemical reaction, the starting molecules are called substrates. The enzyme interacts with a substrate, converting it into a new product. Most enzymes are named by combining the name of the substrate with the -ase suffix (e.g., protease, urease). adialiveWebEnzymes are folded into complex 3D shapes that allow smaller molecules to fit into them.
