Enzymatic substrates in microbiology

WebSep 17, 2024 · A substrate is a molecule that an enzyme reacts with. The enzyme’s active site, or the location where weak bonds between the two molecules can form, is loaded with a substrate. An enzyme substrate complex is formed, and the enzyme’s pressures on the substrate drive it to react and become the planned reaction’s result. Table of Contents … Web4.6 Enzymes. 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. Enzymes facilitate chemical reactions by binding to the reactant molecules, and holding them in such a way as to make the ...
