Question

In ATP, high energy bond is present between

• A. Nucleoside and phosphate group
• B. Sugar and phosphate group
• C. Base and phosphate group
• D. None of the above

Answer 1

The correct option is D None of the above

ATP is known as energy currency of the cell. It has three phosphate out of which one is directly attached to the ribose with phosphate ester bond and it is low energy bond. The bond between two phosphate groups is a phosphoanhydride bond which is considered as high energy bond. So ATP has two high energy phosphoanhydride bonds.

So, the correct answer is option D.
