Given that the standard free-energy change for the reaction glucose + Pi → glucose 6-phosphate is 13.8 kJ/mol, and the standard free-energy change for the reaction ATP → ADP + Pi is −30.5 kJ/mol, what is the free-energy change for the reaction glucose + ATP → glucose 6-phosphate + ADP?

The pressure-flow model explains phloem translocation as a flow of solution (bulk flow) driven by an osmotically generated pressure gradient between source and sink.
a) Phloem translocation, both active and passive mechanisms were considered. All theories, both active and passive, assume an energy requirement in both sources and sinks.
b) In sources, energy is necessary to move photosynthate from producing cells into the sieve elements. This movement of photosynthate is called phloem loading.
c) In sinks, energy is essential for some aspects of movement from sieve elements to sink cells, which store or metabolize the sugar. This movement of photosynthate from sieve elements to sink cells is called phloem unloading.
d) The Active mechanisms of phloem transport further assume that energy is required in the sieve elements of the path between sources and sinks simply to maintain structures.
From the given statements find out the correct for pressure-flow model.
