A Very Appropirate Analogy......a +

a: Catalyst ~
b: minister at a wedding

What: "A catalyst is like a minister at a wedding ceremony because the minister causes the ceremony to take place, has a key role in determining how quickly the ceremony takes place, and is not himself permanently changed as a result of the ceremony. This is unlike the couple getting married, who are permanently changed as a result of the ceremony!"
