Which of the following is not a potential mechanism to activate protein kinases?
A) Cyclic AMP binding to regulatory subunits on the protein kinase.
B) Binding of a calcium complex to the protein kinase.
C) Binding of inositol phosphate to the protein kinase.
D) All three of these mechanisms activate protein kinase.

Question

Quizplus · Accepted Answer

Binding of inositol phosphate is more commonly associated with signal transduction pathways that lead to the activation of other types of enzymes or proteins, rather than directly activating protein kinases. Protein kinases are typically activated by mechanisms such as cyclic AMP binding or calcium complex binding, not by inositol phosphate.
