Who found lock and key hypothesis?
Emil Fischer
enzymes. …and enzyme, called the “key–lock” hypothesis, was proposed by German chemist Emil Fischer in 1899 and explains one of the most important features of enzymes, their specificity.
What is the lock and key hypothesis?
A theory to explain the mechanism of enzymatic reactions, in which it is proposed that the enzyme and substrate(s) bind temporarily to form an enzyme–substrate complex. Thus the enzyme and substrate(s) are said to fit together as do a lock and a key.
What is lock and key model class 11?
-The enzymes act on the substrate. -One of the modes of enzyme action is the “lock and key” model. -Where the enzyme acts as the key which can be activated by a specific substrate, which is the key. -Only the specific substrate for which the enzyme acts, can fit into the active site.
What is the lock and key theory?
What is Lock and Key? Lock and Key is one of the theories that explain the mode of action of an enzyme which catalyzes a reaction. Emil Fischer proposed this theory in 1894. According to lock and key hypothesis, the binding of the substrate into an active site of an enzyme is equalized into the lock and key mechanism.
How is the lock and key analogy not perfect?

How did we use the lock and key?
– The lock can withstand 10 hammer hits without failure – The lock is tested to 250,000 open/close cycles to determine its reliability – The bolt projecting of the lock is 1 inch into the doorframe
