Answer:
The overall formula for photosynthesis is:
6CO2 + 6H2O + light energy → C6H12O6 + 6O2
This equation shows that during photosynthesis, carbon dioxide and water are converted into glucose (C6H12O6) and oxygen, with the help of light energy.
The overall formula for cellular respiration is:
C6H12O6 + 6O2 → 6CO2 + 6H2O + energy (ATP)
This equation shows that during cellular respiration, glucose and oxygen are converted into carbon dioxide, water, and energy in the form of ATP.
It's important to note that the process of photosynthesis and cellular respiration occur in different organelles of a cell, in photosynthesis it occurs in chloroplast in plants and in cellular respiration it occurs in mitochondria. Also, Photosynthesis is an endothermic process while cellular respiration is an exothermic process.
