What is an important function of mitochondria?
a. converting chemical energy from atp into chemical energy in glucose products
b. converting chemical energy from glucose products into chemical energy in atp
c. converting energy from sunlight into chemical energy in glucose products
d. converting energy from sunlight into chemical energy in atp

The best answer is B.

Chemical energy found in glucose and other nutrients is used by the mitochondria to make ATP.  Mitochondria are commonly referred to as the powerhouses of a cell because they are responsible for making ATP, the cell's main energy carrying molecule.

ATP represents the short - term stored energy of the cell. Cellular respiration is the process of making ATP using chemical energy found in glucose and other nutrients. In mitochondria, this process uses oxygen and produces carbon dioxide as a waste product.
