<h2>Adenylyl Cyclase</h2>

Explanation:

The tumor cells most likely have an increased activity of enzyme Adenylyl cyclase.

Since the G alpha-S subunit lacks the GTPase activity, the GTP will not be hydrolized to GDP.As a result the activity of G protein or G subunit will not be inhibited. Thus their respective enzymes will remain active.

An increased activity of Gs Subunit  will thus lead to increased activity of enzyme adenylyl cyclase.
