Does the following applied to acid-base , covalent , or metal ion catalysis or all of them?

-may use amino acids such a aspartate or lysine
-lowers the energy or stabilizes the transition state or intermediate.
-may take part in interactions involving Fe2+

Acid-base, covalent

covalent

-may take part in interactions involving Fe2+

Acid-base, metal ion catalysis

Hey bio_man,

They only have options for:

A) Acid base catalysis
B) Covalent catalysis
C) Metal ion catalysis
D) all

...on a side note..
I thought the amino acid and lowers the energy one applies to all of them? what do you think?

Hey, if it is an either/or ordeal, than by elimination, may use amino acids such a aspartate or lysine should be (D), since I know for sure it is both (A) and (B).

Lowers the energy or stabilizes the transition state or intermediate = (B)
Recall: Serine, cysteine, lysine, and histidine can participate in covalent catalysis.

May take part in interactions involving Fe2+ = (C); Though it can be (C)+(A) also, but not (B). Go with (C).

Is this biochemistry? Sorry bout the mix-up Undecided.

so there is something not right in this...wasnt correct when i submitted it online

i think it might have to do something with the cofactor statement??

"catalyst retains its orginal form" should be in the "ALL" category because a catalyst they are referringin to is an enzyme, remeber an enzyme is never "consumed"

Nucleophile statement should be in acid/base

Cofactor statement should be covalent catalysis
