Title: catalysis Post by: chels194 on Oct 5, 2010 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+ Title: Re: catalysis Post by: bio_man on Oct 5, 2010 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 Acid-base, covalent -lowers the energy or stabilizes the transition state or intermediate. covalent -may take part in interactions involving Fe2+ Acid-base, metal ion catalysis Title: Re: catalysis Post by: chels194 on Oct 5, 2010 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? Title: Re: catalysis Post by: bio_man on Oct 5, 2010 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 :-\. Title: Re: catalysis Post by: chels194 on Oct 5, 2010 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?? Title: Re: catalysis Post by: star on Oct 6, 2010 "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 |
