Clarification of Question by paulinej-ga on 21 Mar 2005 01:43 PST

Apologies to those who thought it was under priced, I do not work in $
normally, hope this is more apropriate

1) There is a relatively high activation energy
2) The ignition source supplies the necessary activation energy
3) The process is enzymatic

and, this isn't a $5 question if you want a real answer, this is at
least  three questions.
