In organisms other than plants, when and where is the most atp produced?
in thylakoids, during photosynthesis
in nuclei, during cellular respiration
in chloroplasts, during photosynthesis
in mitochondria, during cellular respiration

The correct answer is in mitochondria, during cellular respiration.

Explanation:

The mitochondria is the place where the energy of the cells is created. ATP (Adenosine Triphosphate) is the fundamental piece in obtaining energy from the cell in animals, and is produced with the energy that is found in food.

The same thing that happens in plants with chloroplasts, happens in other living beings with mitochondria, where the stored ATP molecules are going to be used to supply energy.

The production of ATP in mitochondria is done through respiration, where oxygen is used to produce energy. Through this breathing process, ATP is produced faster and easier.
