Is an enzyme simply an organic catalyst?

>> No.6378786

Yes

>> No.6378787

>>6378781
Yes. That's the definition of enzyme. Specifically, it's a catalyst made of amino acid chains.

>> No.6378789

If you want to think about it that simply then sure, that's pretty much what they are.

>> No.6378822

>>6378781
Yes. But no.

Must enzymes are able to exquisitely regulated by a variety of mechanisms. "Simple" catalysts do not have such properties.

>> No.6378835

>>6378781
Yup.
Although you really shouldn't use the word simply to describe an enzyme.

>> No.6378842

>>6378822
there is no requirement for catalysts to not be regulated

the only thing that matters for whether something is a catalyst is whether it lowers Ea without being consumed

>> No.6378846

>>6378842
It also has to not be consumed in the reaction it catalyzes in order to be called a catalys. But yeah, regulation doesn't matter.

>> No.6378869

>>6378781

Sometimes. A lot of them would be considered "inorganic" like P450 (iron porphyrin), nitrogenase, oxygenases, because a metal center is the site of catalysis.

>> No.6378892

>>6378846
Is heat a catalyst?

>> No.6378893

>>6378892
No, it's a reactant or a product of a reaction.

>> No.6378913

>>6378842
I am quite aware of that.

My point was that they are not "simple" catalysts. Emphasis on "simple".

Sorry you missed that.

>> No.6380218

yes, look up the definition

>> No.6380234

>>6378893
Are you dumb?
