The answer is the fourth one: Adenosine triphosphate.

Explanation for each option:

  1. RNA: RNA (ribonucleic acid) is primarily involved in coding, decoding, regulation, and expression of genes. It is not directly responsible for storing and releasing energy for cellular chemical reactions.

  2. Triglycerides: Triglycerides are a type of fat (lipid) found in your blood. They are used for long-term energy storage, but they are not nucleotides and do not directly release energy for cellular chemical reactions.

  3. DNA: DNA (deoxyribonucleic acid) contains the genetic blueprint for the development, functioning, growth, and reproduction of all known living organisms and many viruses. It is not involved in the direct release and storage of energy for cellular chemical reactions.

  4. Adenosine triphosphate (ATP): ATP is a nucleotide that serves as the primary energy carrier in cells. It stores and releases energy by breaking and forming its high-energy phosphate bonds, making it essential for cellular chemical reactions.

Summary: Adenosine triphosphate (ATP) is the nucleotide responsible for releasing and storing energy for cellular chemical reactions.
