E) adenylyl cyclase activity and the conversion of cAMP to AMP

Question

Quizplus · Accepted Answer

GTPase activity is the hydrolysis of GTP to GDP, which is a fundamental mechanism in intracellular signaling pathways. Kinase activity is the addition of a phosphate group to a molecule, and it can be either serine/threonine or tyrosine specific. Phosphodiesterase activity removes a phosphate group from a phosphodiester bond, which plays a crucial role in regulating intracellular levels of cAMP and cGMP. Phosphorylase activity is the hydrolysis of glycogen to glucose, whereas adenylyl cyclase activity catalyzes the conversion of ATP to cAMP.
