Question

The import cycle of cargo or molecule inside the nucleus requires the hydrolysis of  ___

(a) 1 GTP

(b) 1 ATP

(c) 2 GTPs

(d) 3 GTPs

I have been asked this question in a job interview.

This interesting question is from Nucleus in section Nucleus & Aerobic Respiration of Cell Biology

Answer 1

The correct option is (c) 2 GTPs

Best explanation: The import of cargo or molecule inside the nucleus is an active transport. This is because the whole of import cycle needs the energy from the hydrolysis of two Guanosine triphosphate (GTP) molecules.
