Which molecule is the "energy cash" of the cell?
a. carbon dioxide
b. glucose
c. atp
d. oxygen?

The correct answer is C) ATP.

The molecule that is the "energy cash" of the cell is ATP.

ATP stands for Adenosine Triphosphate is the "energy cash" or "molecular currency" of the cells. It transfers energy between cells. ATP is so important for the cell because it can store and then transport chemical energy and helps in the synthesis of nucleic acids.  

hola,

i hate my life too. (like jayfeather hates his blindness x3)

the of atp are the key to its ability to store and supply energy;

phosphate

the phosphate groups of atp are the key to its ability to store and supply energy. atp releases energy when it breaks bonds between its phosphate groups.
