Question

In ATP, high energy bond is present

• A. Between nucleoside and phosphate group
• B. Between sugar and phosphate group
• C. Between base and phosphate group
• D. Between phosphate group
  

Answer 1

The correct option is D Between phosphate group

ATP is known as the energy currency of the cell. It is an unstable molecule which gets hydrolyzed to ADP and inorganic phosphate during metabolic endothermic reactions. The high energy bonds exist between phosphate molecules of ATP. The bonds between phosphate molecules are called phosphoanhydride bonds.

So, the correct answer is 'Between phosphate group'.
