Question

Which statement best describes the purpose of ATP?

A. It uses DNA and RNA to make proteins
B. It helps make glucose out of sunlight and water
C. It releases energy that is used by cells
D. It breaks down into carbohydrates and lipids

Answer 1

It should be C. ATP supplies energy for many biochemical cellular processes by undergoing enzymatic hydrolysis especially to ADP —called also adenosine triphosphate.

Answer 2

Answer: C. It releases energy that is used by cells.

Step-by-step explanation:

Adenosine triphosphate is a complex chemical molecule it provides energy to conduct various processes occurring in the living cells like nerve impulse generation, muscle contraction, and chemical synthesis. It is called as the molecular unit of currency.

It forms in the process of cellular respiration in which the glucose is oxidized and break down so as to produce energy in the form of ATP. The ATP is a biomolecule which is formed by the purine base (adenine) and sugar molecule (ribose) along with three phosphate groups.

The ATP hydrolysis is an exothermic reaction which releases energy that can be used by the cell for cellular metabolism.
