<h2>Answer:</h2>
When the bond between the second and third phosphate is broken down in different cellular processes huge amount of energy like 7.3 K cal is released.
<h3>Explanation:</h3>
- ATP is the energy currency for the cells. Cells produce this currency in mitochondria via respiration.
- As the energy is stored in the electrons involved in the boding between Gama phosphate and beta phosphate.
- Formation of this energy requires a huge amount of energy and its breakdown also release that energy.
A reproductive combination between living parent organisms which produces hybrids is: c. when members of closely related species reproduce.
<h3>What is reproduction?</h3>
Reproduction can be defined as a biological process through which all living parent organisms produce their offspring, especially through mating.
