For photosynthesis, ATP helps to provide energy needed for the carbohydrate synthesis in the Calvin/Benson/Bassham Cycle.
And in cellular respiration, they create 36 ATP, that is broken up into three different parts. First, is that they come from glycolysis, which is the first step in breaking down glucose to extract energy for cellular metabolism. Next comes the Krebs Cycle, which oxidizes the pyruvate formed during the glycolytic breakdown of glucose into Carbon Dioxide. Finally, we have the Electron Transport Chain, where a series of complexes transfer electrons from a redox reaction which happens during the aerobic respiration.

The cycle runs like this:
Deoxygenated blood enters from the body to the heart via the superior/inferior vena cava. It goes directly to the right atrium and down to the right ventricle. From there it'll pass through the pulmonary artery into the lungs where diffusion will happen in the capillaries. Gas exchanges will occur and the blood will become oxygenated and return to the heart via the pulmonary vein. From the pulmonary vein it will enter back into the left atrium and then will give the final pump of oxygen rich blood into the aorta and then into the entire body.
