Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Converting ADP into ATP is
A
endergonic
B
exergonic
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -The reverse reaction combines ADP + Pi to regenerate ATP from ADP. Since ATP hydrolysis releases energy, ATP synthesis must require an input of free energy. The phosphorylation (or condensation of phosphate groups onto AMP) is an endergonic process.

Detailed explanation-2: -The hydrolysis of ATP into ADP and inorganic phosphate is an endergonic reaction because there is a negative change in free energy between products and reactants.

Detailed explanation-3: -ATP synthesis is an endergonic reaction because to form a high energy bond, energy is required.

Detailed explanation-4: -In the inner membranes of mitochondria, ADP is converted to ATP through a process called chemiosmosis phosphorylation.

Detailed explanation-5: -The formation of ATP by condensation between ADP and inorganic phosphate is a highly endothermic reaction.
