Which of the outcomes could potentially result if a mutation in the gene encoding the Ga subunit eliminates its GTPase activity? Choose three outcomes. Ga would be ineffective as a signal molecule (that is, it could not activate other proteins). The rate of GTP hydrolysis would increase. The concentration of CAMP in the cell would be continuously elevated. The cell would be unresponsive to molecules that act via CAMP. Go would be activated for an extended period. The signaling pathway could be activated for an extended period, possibly resulting in undesirable cell proliferation.

Q6

Which of the outcomes could potentially result if a mutation in the gene encoding the Go subunit eliminates its GTPase
activity? Choose three outcomes.
G& would be ineffective as a signal molecule (that is, it could not activate other proteins).
The rate of GTP hydrolysis would increase.
The concentration of cAMP in the cell would be continuously elevated.
The cell would be unresponsive to molecules that act via cAMP.
Go would be activated for an extended period.
The signaling pathway could be activated for an extended period, possibly resulting in undesirable cell proliferation.
