When cellular respiration occurs, what is the primary molecule used to store the energy that is released?A. mRNAB. ATPC. PhosphateD. AMP

Answer

The primary molecule used to store the energy that is released during cellular respiration is B. ATP (Adenosine Triphosphate).

ATP serves as the main energy carrier in all living organisms. During cellular respiration, glucose is broken down, and the energy released during this process is used to synthesize ATP from ADP (Adenosine Diphosphate) and inorganic phosphate. ATP then acts as a readily available energy source for various cellular processes, such as muscle contraction, active transport, and biosynthesis.

In contrast, mRNA is involved in protein synthesis, phosphates are components of ATP and ADP, and AMP (Adenosine Monophosphate) is a lower energy form compared to ATP. Hence, ATP is the correct answer as it is the energy currency of the cell.
