ATP synthase', 'role': 'user'}, {'content': "Answer: B \nExplanation: Markers of plasma membrane areMarker enzyme for mitochondria is ATP SynthaseMarker enzyme for golgi complex is GalactosyltransferaseAdenylyl cyclase appears to be a good marker enzyme for plasma membranes5'-Nucleotidase (5NT) is an intrinsic membrane glycoprotein that is present as an enzyme in a wide variety of mammalian cells. It facilitates the hydrolysis of the phosphate group from 5'-nucleotides, resulting in corresponding nucleosides.", 'role': 'assistant'}]
