Identify the correct chemical reaction for photosynthesis

• 6CO2 + 6H2O + light energy → C6H12O6 + 6O2

• Light energy+ C6H12O6→ 6CO2 + 6H2O

• 6CO2 + 6H2O→ 6CO2 + 6H2O + light energy

• C6H12O6 + 6O2 → 6CO2 + 6H2O + light energy

Identify the correct chemical reaction for cellular respiration.

• ATP+ C6H12O6→ 6CO2 + 6H2O

• C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP

• 6CO2 + 6H2O + ATP → C6H12O6 + 6O2

• 6CO2 + 6H2O→ 6CO2 + 6H2O +ATP
