How can enzyme activity be regulated
WebIonizable side groups located in the active site must have a certain charge for the enzyme to bind its substrate. Neutralization of even one of these charges alters an enzyme’s catalytic activity. An enzyme exhibits maximum activity over the narrow pH range in which a molecule exists in its properly charged form. Web19 de jun. de 2014 · See answer (1) Best Answer. Copy.
