This sounds like an exam question you really need to look this up yourself.

Sounds likely, Drc! If not, Guest16, please add your own comment, or amend your question to sound less telegraphic. We're happy to answer any honest question, but we refuse to do students' homework for them.

"Homework" was what I thought too. And it's a badly phrased question too. "Pickaxe and shovel" is the wrong answer.

I can answer that very succinctly. Enzymes. but you will have to research which ones and on which substrates. I ' not keen on homework either :o)
