Re: speed and specificity of enzymes



I said that 2nd order autopoietic systems not being
able to frozen. Any living systems without a nervouse
system is first order autopoietic. 

I am not aware of any instances that revive a frozen
2nd order autopoietic systems such as a mosquito or a
roach that are small enought to be frozen instantly.

Goto your yard to get a few grasses and freeze them.
My bet is that you can revive them but never a
mosquito no matter how samll they are.

I have discussed with two biology professors who told
me examples of freezing unicelled organisms and the
reason we can not freeze a human yet is because we can
not freeze it instantly. But I do not argue with them.

rotifera is 1st order autopoietic system albeit its
multicellular form but not evolved with a nervous
system yet. Its  behavior is no different from a
flagellar.
