Enzymes: principles and biotechnological applications

WebEnzymes are the catalysts involved in biological chemical reactions. They are the “gnomes” inside each one of us that take molecules like nucleotides and align them together to create DNA, or amino acids to make proteins, to name two of thousands of such functions. 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. how is light absorbed in photosynthesisWebEnzymes are biological catalysts (also known as biocatalysts) that speed up biochemical reactions in living organisms, and which can be extracted from cells and then used to catalyse a wide range of commercially important processes.
