STATEMENT-1 : According to the lock - and - key model. When the key (substrate) fits the lock (active site) the chemical change bedins. STATEMENT-2 : Modern X-ray crystallographic and spectroscopic methods show that in many cases, the enzyme changes shape when the substrate lands at the active site. STATEMENT- 3 : Enzyme catalysed reactions processed through a fast, reversible formation of an enzyme substrate complex, followed by a slow conversion to product and free enzyme.
