Catalyze

... and perhaps a working ER to do this. The reason behind RNA being the first is because RNA can also form into ribozymes, simple enzymes that can catalyze peptide synthesis.

... a homework question. This is a study effort for a big upcoming test. Can enzymes use energy (like ATP) in powering their reactions? How do they catalyze reactions if they don't actively use energy like ATP??????

... in CoA just reflects the fact that it's part of the catalyst and catalysts by definition are regenerated and left unchanged by the process they catalyze. Here is a description of the pyruvate dehydrogenase complex reactions to form acetyl-CoA. http://rpi.edu/dept/bcbp/molbiochem/MBWeb/mb1/part2/krebs.htm ...

... as there is only one enzyme (doing the reactions)" OK, I can't guarantee that's what's going on here, but the same enzyme can and often does catalyze the forward and the reverse reactions. It is certainly possible for the forward and reverse reactions to "cancel out." That's the ...

... binds to one active site, the enzyme undergoes a conformational change, the active site for the substrate is altered, and the enzyme cannot catalyze the reaction..." Clearly, in this book, allosteric and noncompetitive inhibition sound very similar. Can someone explain to me the difference ...
