What is energy coupling? a. the hydrolysis of atp to adp + p b. the use of energy released from an exergonic process to drive an endergonic process c. the energetic relationship between the reactants and products in an exergonic reaction

The correct answer is A   The use of energy released from an  Exergonic reaction to drive an Endergonic reaction the process that requires energy.

Explanation:

Exergonic reaction is a type of chemical reaction that generates energy on the other hand Endergonic reaction requires energy in form of ATP to occur in a biological system.

             The ist step of Glycolysis is an important example to study coupling reaction because the the direct addition of phosphate group to glucose molecule is Thermodynamically unfavorable because the free energy change of this reaction is positive.

                     To carry out this reaction in a thermodynamically favorable manner Glucose reacts with inorganic phosphate in presence of  ATP resulting in the hydrolysis of the ATP by the removal of terminal phosphate group from ATP  into ADP and Pi  and addition of the inorganic phosphate to the C6 of glucose molecule resulting in the formation of glucose 6 phosphate.
