Isocitrate dehydrogenase is regulated via negative feedback by _____ and NADH

The enzyme glutathione _____ requires a molecule of NADPH, which is provided by the activity of the enzyme G6PD

_____ activates factor XII, which initiates the intrinsic pathway of the coagulation cascade

Dopamine in the CNS may be degraded to _____ via the enzyme catechol-O-methyltransferase (COMT)
