None of the above
|
Detailed explanation-1: -So, the correct answer is ‘The hydrolysis of ATP into ADP and inorganic phosphate is an exergonic reaction because there is a negative change in free energy between products and reactants’
Detailed explanation-2: -If a cell needs to spend energy to accomplish a task, the ATP molecule splits off one of its three phosphates, becoming ADP (Adenosine di-phosphate) + phosphate. The energy holding that phosphate molecule is now released and available to do work for the cell.
Detailed explanation-3: -The formation of ATP by condensation between ADP and inorganic phosphate is a highly endothermic reaction.
Detailed explanation-4: -So, the correct answer is ‘Endergonic; Chemiosmosis’
Detailed explanation-5: -The hydrolysis of ATP is an exergonic reaction. The hydrolysis of ATP into ADP (adenosine diphosphate) and Pi (inorganic phosphate) is an exergonic reaction because it results in the release of energy. This released energy is used for the various life processes occurring in a living cell.
