Indeed, I supposed that a catalyst as used in chemistry ( EG. Haber
Process? )
might be different from enzymes?

No, Pepsin is an excellent example :>
It is the most extreme example of WHY an enzyme might require an acidic
condition to operate,
in fact, I think I already posted a site to this thread which explained how
pepsin is "activated"...
I am pretty sure you have just confirmed my point, which, to be frank, is
what the objective of this thread is,
I doubt my opponent is interested greatly in biology...
