Photosynthesis
Happens in chloroplast
3 reactants of photosynthesis: chlorophyll, water, light energy, and carbon dioxide are reactants.
products are glucose (sugar), oxygen and water.
Cellular Respiration:
Happens in mitochondria
Oxygen and glucose
main product of cellular respiration is ATP; waste products include carbon dioxide and water.
What four substances are recycled during photosynthesis and respiration? Carbon dioxide , water , glucose , oxygen. The four substances recycled during photosynthesis and respiration are: carbon dioxide (CO2), which is emitted as waste in cellular respiration and used by plants to make glucose, oxygen (O2), which is emitted as waste by plants and taken in by animals to allow cellular respiration to proceed, glucose (C6H12O6), which is consumed in cellular respiration and made from CO2 in photosynthesis and water (H2O), which is a waste product of cellular respiration but required for photosynthesis and a host of other reactions.
