Question

which statement explains how food provides energy to cells?
o food stores energy which is used by cells when the food is broken apart during digestion.
o food stores energy which is used to form adenosine diphosphate (adp), a molecule that provides energy to cells.
o food stores energy which is used to form adenosine triphosphate (atp), a molecule that provides energy to cells.
o food stores energy which is used by cells when the food is absorbed by stomach acid.

Explanation:

Food contains energy - rich molecules. During cellular respiration, the energy in food is used to produce adenosine triphosphate (ATP), which is the energy - currency molecule for cells. ADP is involved in the ATP - ADP cycle but is not the final energy - providing molecule formed from food energy. Digestion breaks food into smaller components, but it's the formation of ATP that directly provides energy to cells. Stomach acid is for digestion and not the mechanism by which cells get energy from food.

Answer:

Food stores energy which is used to form adenosine triphosphate (ATP), a molecule that provides energy to cells.
