Answer:
b. ATP
Explanation:
ATP is an acronym used to indicate the adenosine triphosphate molecule (Adenosine TriPhosphate). This molecule is the main form of chemical energy since its hydrolysis is highly exergonic. This means that by undergoing the hydrolysis process (fission by water action), this molecule releases a large amount of free energy.
ATP is essential for the functioning of all living organisms, basically this molecule participates in any mechanism of metabolism, not only in humans, but in any living creature. An example of this is that motile sperm in fungi, plants, and animals depend upon ATP to drive the microtubule interaction in their flagella.
