Question

when an organism performs cellular respiration, ______ enters the mitochondria and its potential energy is converted to molecules of ______, which stores the energy in a form more useful to the organism. heat; sugar adenosine triphosphate (atp); sugar sugar; heat sugar; adenosine triphosphate (atp)

Explanation:

Cellular respiration uses sugar as a fuel source. In the mitochondria, the potential energy in sugar is converted into adenosine triphosphate (ATP), which is the energy - currency molecule for the organism. Heat is a by - product of cellular respiration, not the molecule that stores useful energy. ATP stores energy in a form that can be readily used by the cell for various processes.

Answer:

D. sugar; adenosine triphosphate (ATP)
