Answer:
Endergonic.
Explanation:
Product produced by Endergonic reaction have more potential energy than reactants. Energy is required for organisms to grow because it's necessary for production of new materials. Endergonic reaction have two main purpose in biology:
1) Helping to release energy which is stored in food molecules and helping organism to survive without harvesting the energy directly comes from sunlight.
2) Helping to create building blocks of life such as DNA, RNA, and proteins created with the help of reaction which forms new bonds present between chemical building blocks. These reactions are generally endergonic reactions.
Example of endergonic reactions are:
1) DNA-RNA synthesis.
2) Protein synthesis.
3) Fatty acid synthesis.
