The chemical equation for cellular respiration is: glucose + oxygen > your mama

carbon dioxide + water
sunlight --->glucose + oxygen

oxygen + carbon dioxide glucose + water

glucose + oxygen --->carbon dioxide + water + ATP (energy)

The last one

Explanation:

Glucose+oxygen> Carbon dioxide+ water+ ATP(energy)

the supermassive black hole is in the middle of the galaxy.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
