Re: speed and specificity of enzymes

Tim,

I have disscussed the issues you raised with some
biochemist (post doc). We reached concensus that there
is a difference between sleeping and being frozen.  

The freeze tolerance animals like wood frogs you
mentioned are really sleeping under lower temperature
than you sleep with. The freeze of cells of a wood
frog will kill it if you read the materal carefully.
