Question

Which of the following does NOT model photosynthesis? (1 point)
Responses

carbon dioxide + water + light YIELDS sugars + oxygen
carbon dioxide + water + light YIELDS sugars + oxygen

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

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

6CO2 + 6H2O + NADP+ + light → C6H12O6 + 6O2 + NADPH

Answer 1

The option that does NOT correctly model photosynthesis is:

**6H2O + 6O2 + light → C6H12O6 + 6CO2**

This equation is incorrect because it suggests that water (H2O) and oxygen (O2) are the reactants, which is not how photosynthesis is represented. In reality, photosynthesis involves carbon dioxide (CO2) and water (H2O) as reactants, producing glucose (C6H12O6) and oxygen (O2) as products. The correct balanced equation for photosynthesis is:

**6CO2 + 6H2O + light → C6H12O6 + 6O2**

The last option including NADP+ is a more detailed representation of the process, but it still accurately models photosynthesis.
