How are photosynthesis and cellular respiration connected at the molecular level?

Answer 1

The chemical formula for photosynthesis is: 6 CO2+ 6 H2O →C6H12O6 + 6 O2

Carbon dioxide + Water + Light energy → Glucose + Oxygen

The chemical formula for cellular respiration is: 6 O2 + C6H12O6 → 6 CO2 + 6 H2O

The two are {semi} opposites of each other; photosynthesis makes Glucose from Sunlight, and cellular respiration breaks Glucose down to form Atp - i.e. Useable Energy.

Answer 2

Together they form the carbon cycle in the nature. It is the beauty of nature. You get carbon bi oxide and water from glucose, in case of the animals. You get glucose from carbon bi oxide and water in case of the plants. The cycle continues. It is there from three and half billion years.

Answer 3

Photosynthesis produces glucose and oxygen by capturing sunlight energy and converting it into chemical energy. This glucose is then used as a substrate for cellular respiration, where it is broken down to generate ATP through a series of chemical reactions. Oxygen produced during photosynthesis is used in cellular respiration as an electron acceptor in the electron transport chain. Both processes are interconnected through the exchange of energy and molecules.
