What characteristic of enzymes allows it to be highly specific in the reaction they catalyze

Enzymes are highly specific for the reaction they catalyze. Their structure allows them to highly specific as there are various enzyme theories that defines its selectivity.

One of them is Lock and Key model: In it a enzyme structure defines  which substrate can  fit into it enzyme is the lock and substrate is the key. So only a correctly size substrate can fit into the active site of enzyme.

It’s A

Explanation: I took the quiz

beta decay is the answer

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.
