Question

What equation best summarizes the overall reactions of photosynthesis?

A) 6 CO2 + 6 H2O → C6H12O6 + 6 O2
B) 2 H2O + 2 NADP+ + 3 ADP + 3 P_i → 2 NADPH + 2 H+ + 3 ATP + 3 H2O
C) C6H12O6 + 6 O2 → 6 CO2 + 6 H2O
D) 12 H2O + 6 CO2 + light energy → C6H12O6 + 6 O2 + 6 H2O

Answer 1

The equation summarizing the overall reactions of photosynthesis is 6 CO₂ + 6 H₂O + Light Energy → C₆H₁₂O₆ + 6 O₂, converting carbon dioxide and water into glucose and oxygen.

Step-by-step explanation:

The equation that best summarizes the overall reactions of photosynthesis is:

6 CO₂ + 6 H₂O + Light Energy → C₆H₁₂O₆ + 6 O₂

This represents the conversion of carbon dioxide and water into glucose and oxygen, using energy from sunlight. Photosynthesis is a complex process involving two main stages: the light reactions and the Calvin cycle. Despite the complexity of the process, with many reactions and intermediates, the net effect is shown by the simple equation above.

Correct Option: A) 6 CO₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂
