How does cellular respiration compare with photosynthesis??
Cellular respiration combines oxygen with glucose in the mitochondria to produce ATP; carbon dioxide and water (along with a little heat) are produced as well. Photosynthesis uses energy from sunlight to build glucose and release oxygen from carbon dioxide and water. Essentially, cellular respiration uses the products of photosynthesis and photosynthesis uses the products of cellular respiration as its starting point.
