The Mitochondria of an animal cell is responsible for producing ATP in an animal while the Chloroplast of a plant cell is responsible for producing ATP in a plant.
More specifically, for plants, the Glucose which is produced in the light stage of photosynthesis (C6H12O6) is responsible for the production of adenine triphosphate (ATP), which is where a plant gets the energy to produce food in the dark stage of photosynthesis.
The answer you are looking for is Glucose. The Glucose molecule is most responsible for the production of ATP.
C6h12o6
Mitochondria is responsible for ATP production.
Phosphate
The majority of ATP production occurs during electron transport, which produces 34 ATP molecules per glucose molecule.
Mitochondria are the sites of certain stages of respiration. They are therefore responsible for the production or the energy-carrier molecule - ATP.
Mitochondrion
Sugar
The organelle "Mitochondria" is responsible for cellular respiration and the production of Adenosine Triphosphate (ATP)
Mitochondria are often called the power plants of the cell. They are responsible for the greatest production of adenosine triphosphate, the molecule which carries energy for most of the cell's functions.
The number of ATP molecules that are produced depends on the type of molecule broken down -- from my biology book
ATP
Total (gross ) ATP production by oxidative process is 36 .
