cAMP 2nd Messenger Pathway and Experiments

... so obviously it was not. Probably the activity remained even after the mutation C. not mutated? Other homologues? D. ATP is substrate, Mg2+ is cofactor, GTP triggers the G-proteins E. Other homologues are present?

Re: Gluconeogenesis

... do is oxidize the hydroxyl group at the C2 carbon. On the other hand, Alanine needs to be deaminated via Alanine transminase, that uses PLP as a cofactor to transfer the amino group to a-ketoglutarate. Alanine then needs to be hydrolyzed and oxidized to yield Pyruvate. It's probably simpler and ...

Mastermix in PCR

I agree with what JackBean said, however it does not answer your question. MgCl2 is a required cofactor for the Taq Polymerase to work. The activity of the Taq polymerase is sensitive to the concentration of MgCl2. The higher the concentration of the MgCl2, the more active ...

Molecular gene (genome) concept scientifically untenable

... the afflicted person also smokes. So, how does smoking cause cancer? Gene expression could be influenced by many things other than proteins called cofactors. Perhaps tobacco contains a chemical that acts as a cofactor for cancerous genes. Therefore, we conclude that smoking causes cancer. The question ...
