STATEMENT-1 : According to the lock - and - key model. When the `key` (substrate) fits the `lock` (active site)
the chemical change begins.
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 proceed through a fast, reversible formation of an enzyme
substrate complex, followed by a slow conversion to product and free enzyme.
