Chemical models of enzymes
WebAug 16, 2024 · The Substrate-Enzyme Binding. Originally two models were proposed to explain how an enzyme binds its substrate. The Lock and Key Model . In the lock-and-key model proposed was proposed by Emil Fischer in 1894. According to the model, the shape of the substrate and the active site of the enzyme are thought to fit together like a key … 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.
