Question

Is ATP formation exergonic or endergonic?

Answer 1

ATP:

1. ATP is called the energy currency of the cell.
2. Chemically it is a nucleotide.
3. In ATP three phosphate groups are linked with adenosine through the phosphodiester bond.
4. These phosphodiester bonds are high energy bonds.
5. ATP synthesis is an endergonic reaction because to form a high energy bond, energy is required.

ADP + P_i + 2H⁺_out ⇌ ATP + H₂O + 2H
