Answer 1

Explanation:

It explains enzyme specificity .

Just like a particular key can open a lock, a specific enzymes act on a specific substrate. Here, lock is the substrate and enzyme is the key.

The specific action of an enzyme with a single substrate can be explained using a Lock and Key analogy first postulated in 1894 by Emil Fischer. In this analogy, the lock is the enzyme and the key is the substrate. Only the correctly sized key (substrate) fits into the key hole (active site) of the lock (enzyme).
