Question

ATP is classified as an energy-rich compound because ________. (A) It complexes with Mg2+ (B) Its complete oxidation to carbon dioxide releases a large amount of energy (C) It has a relatively low free energy of hydrolysis (D) Of the free energy released from cleavage of the phosphoanhydride bond

Answer 1

The correct answer will be option D.

Step-by-step explanation:

Adenosine triphosphate or ATP is known as the energy molecule of a cell because it provides the energy to do work.

ATP is a nucleotide molecule formed by linking of the adenine base to ribose sugar and three phosphates. The energy is stored between the phosphoanhydride bonds between these three phosphates. The hydrolysis of ATP releases adenosine diphosphate (ADP) and the free stored energy in phosphoanhydride bonds which further hydrolysed to form adenosine monophosphate (AMP) and free stored energy in bonds.

Thus, option D is the correct answer.
