WebAccording to the induced fit theory by Daniel Koshland, binding of substrate to the enzyme brings a conformational change in the enzyme to either enhance or inhibit its activity. The active site keeps changing its shape until it is bound to the substrate, the final binding gives a proper shape to the enzyme. WebKoshland proposed the induced fit theory in 1958. Part of an enzyme where substrate molecules get attached is known as an active site. On attachment to the active site, the … gelish led nail polish
