Where in the cell was the atp produced?

In the mitochondria  and cytoplasm organelles.

Explanation:

During the respiration process, the cell gets into their structure glucose molecules to obtain their energy, it transport from the membrane, on the cytoplasm the process called glycolisis, started and then in the inner part of the mitochondria the rest of the respiration process ends.

Respiration process requires oxygen, depending the living thing, it can be obtain from one glucose molecule,  4 until 32 ATP molecules. The number of ATP  molecules will be depending the needs of energy of the living thing.

not sure if this what   you'r looking for would be percent composition
