Question: The GTP regulating protein GNOM is critical for proper cellular response to auxin. In particular,…

The GTP regulating protein GNOM is critical for proper cellular
response to auxin. In particular, GNOM helps induce vesicle
trafficking of auxin transporters to the correct part of the plasma
membrane. Suppose that the signaling pathway that initiates vesicle
trafficking of auxin transporters is induced by auxin itself
binding an extracellular receptor, which triggers a signal
transduction pathway that includes GNOM, the GTP-binding protein
GNOM regulates, and a phosphatase. The GTP-binding protein directly
promotes vesicle trafficking, and GNOM must be phosphorylated to be
functional. a. Put the transduction molecules in the correct order.
b. What type of GTP-regulating protein is GNOM?
