When a variable is allocated, a lock value is created and placed both into the variable's cell and into the pointer's key ...
This is often referred to as "the lock and key" model. [1]: 8.3.2 This early model explains enzyme specificity, but fails to explain the stabilization of the transition state that enzymes achieve. [41]
