Enzyme affinity definition
WebEnzymes (/ ˈ ɛ n z aɪ m z /) are proteins that act as biological catalysts by accelerating chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into … WebAffinity can be considered as capability of recognizing the specific substrate or how strongly the enzyme binds with the substrate.
