Answer:
Glucose
Step-by-step explanation:
Photosynthesis is the process of the transformation of the light energy from the Sun into stored chemical energy that can serves as the major source of energy in the food chain
The overall chemical equation for photosynthesis reaction can be presented as follows;
6CO₂(g) + 12H₂O(l) + Light Energy → C₆H₁₂O₆ + 6O₂ + 6H₂O
During cellular respiration, the energy in the glucose, C₆H₁₂O₆, is converted to energy stored in Adenosine Triphosphate (ATP) molecules which are released when the the ATP is converted into Adenosine Diphosphate (ADP)
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + Energy containing ATP
