Object Type:
reac
Description:
Chemical reaction object. Works with pools to provide kf
and
kb. Reacs calculate the changes in concs for each pool hooked
into them. The pool is responsible for adding up all the
up and down changes resulting from various reactions it is
involved in. Each reac can handle any number of substrates
and products, though reactions of order greater than 2 are
rare. Any number of reacs can be hooked up to a given pool.
The generic reaction scheme is:
kf
Substrate1 + S2 + .. <----> Prd1 + Prd2 + ...
kb

kf
Forward rate constant. Units depend
on the order of the reaction, ie,
the number of molecules on the
left hand side. First
order is sec^-1, second order is
sec^-1.num^-1, etc.
Backward rate constant. Units depend
on the number of molecules on the
right hand side, in a similar way.
Internal state variables, used to
communicate with pools. A represents
increase in the pool n, B is the
decrease.
