Question

during the metabolism of glucose, the conversion of glucose to glucose 6 - phosphate cannot proceed without the hydrolysis of atp. which is a reason for this? the reaction is spontaneous. the reaction is endergonic. chemical energy can only be converted to chemical energy. glucose 6 - phosphate has a lower free energy than glucose. the reaction involves a large decrease in free energy.

Explanation:

Endergonic reactions require an input of energy to proceed. The conversion of glucose to glucose - 6 - phosphate is endergonic and thus cannot proceed without an energy source like the hydrolysis of ATP. Spontaneous reactions have a negative change in free energy and do not require external energy input. Chemical energy can be converted in various ways, and glucose - 6 - phosphate has higher free energy than glucose in this context. A large decrease in free energy would drive a reaction spontaneously, but this is not the case for the conversion of glucose to glucose - 6 - phosphate.

Answer:

The reaction is endergonic.
