catalyst

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!"

What: "a catalyst is like a tool, perhaps a pair of scissors you use to cut paper. The "reaction" is taking sheets of paper and converting them to different shapes. You and your scissors make this "reaction" happen, but neither you nor the scissors are "used up" in the reaction."

What: A toolbox starts out filled, but you take away tools like a screwdriver or a wrench. The toolbox is changed in the middle of the reaction, but is 'put together' again and comes out the same as it came in. While it is still possible to hammer in a nail or do the other steps needed in a reaction without a toolbox, it is much more difficult and less likely.
