2. Which type of biomolecule is ATP? Recall the biomolecules include carbohydrates, lipids,
proteins, and nucleic acids.

The correct answer is: ATP is a nucleic acid.

Explanation:

ATP, abbreviated from adenosine triphosphate, is a nucleic acid that has only one nucleotide and, instead of having only one phosphate like DNA and RNA have, has three phosphates attached to its sugar. Having three phosphates is very important for its function as an energy storer and tranferer, because when the phosphoanhydride bond between two of its phosphates breaks there's a rapid energy release that can be used by the cell in many different ways (for example, muscle contraction).

it is called the mitotic spindle
