two questions

[champ]

how does an inorganic catalyst differ from and enzyme?

what coenzymes and found in catalase?

[Porque_Jorge]

From what I know an enzyme is a 'Biological Catalyst' and so there is the difference!!???

Dunno about the second one though...

[Peter Pedant]

bit late

take H202 and manganese

and I dunno catalase....

One is metal, inert, will work at any temp, may form bonds,

the other is a protein, temp sensitive, can be broken down with temp, is very specific for the substrate and notfor the reaction

Drunk, Peter? You are quite right that an enzyme is generally substrate-specific and, since it is a protein, will be denatured (rendered inactive) at around 40 degrees Celsius. I think the reaction you were trying to use as an example of inorganic catalysis was the use of manganese dioxide to catalyse the decomposition of hydrogen peroxide.
