impossible to know
Which photosynthesis equation is correct?
C6H12O6 + 6H2O → 6O2 + 6CO2 + ATP
sunlight + C6H12O6 + 6H2O → 6O2 + 6CO2
sunlight + 6O2 + 6CO2 → C6H12O6 + 6H2O
sunlight + 6H2O + 6CO2 → C6H12O6 + 6O2
Which cellular respiration equation is correct?
C6H12O6 + 6O2 → 6H2O + 6CO2 + ATP
sunlight + C6H12O6 + 6H2O → 6O2 + 6CO2
