What are some facts about Photosynthesis and Cellular Respiration?

Answer 1

Photosynthesis and cellular respiration are connected through an important relationship. This relationship enables life to survive as we know it. The products of one process are the reactants of the other. Notice that the equation for cellular respiration is the direct opposite of photosynthesis:

Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2OPhotosynthesis: 6CO2 + 6H2O → C6H12O6+ 6O2

In our cells, oxygen allows cellular respiration to proceed. Cellular respiration works best in the presence of oxygen. Without oxygen, much less ATP would be produced.Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere. The exchange of carbon dioxide and oxygen during photosynthesis (Figure below) and cellular respiration worldwide helps to keep atmospheric oxygen and carbon dioxide at stable levels.

Hope you do good, Good luck!

Answer 2

Photosynthesis takes in sunlight, carbon dioxide, and water and produces glucose and oxygen as byproducts. Cellular respiration converts chemical energy from oxygen molecules or nutrients into ATP and produces water and carbon dioxide as byproducts. They are sort of opposites, because photosynthesis takes in carbon dioxide & water and releases oxygen when it produces energy, and cellular respiration takes in oxygen and releases carbon dioxide & water when it produces energy.

Good luck!!
