H2O2 is converted to _____ by the enzyme myeloperoxidase (oxidative burst)

_____ is a serine protease that cleaves at the carboxy-terminal of neutral amino acids like alanine and glycine.

_____ and Catalase are two enzymes contained in aerobic organisms

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

Chymotrypsinogen is a _____ whereas its active form Chymotrypsin is a serine protease.

Phosphofructokinase-1 is regulated via negative feedback by _____ and citrate

_____ may be converted to norepinephrine via the enzyme dopamine beta-hydroxylase (with vitamin C as a cofactor)
