Which chemical reaction correctly represents oxygenic photosynthesis in plants and algae?

• A. $2H_{2}O+\mathrm{light}\to 2H_2+O_2$
• B. $C_6{H}_{12}{O}_6+6O_2\to 6C_{0}2+6H_{2}O+\mathrm{energy}$
• C. $6C_{0}2+6H_{2}O+\mathrm{light}\to C_6{H}_{12}{O}_6+6O_2$
• D. $N_2+3H_2\to 2N_{\mathrm{H}}{3}_{\mathrm{}}$

Answer: (C)

Verified step by step guidance

1. Identify the overall process described: oxygenic photosynthesis is the process by which plants and algae convert carbon dioxide and water into glucose and oxygen using light energy.
2. Recall the general balanced chemical equation for oxygenic photosynthesis: \$6\,CO_2 + 6\,H_2O + \text{light energy} \rightarrow C_6H_{12}O_6 + 6\,O_2$.
3. Analyze each given chemical reaction to see which matches this equation, focusing on the reactants (carbon dioxide, water, light) and products (glucose, oxygen).
4. Exclude reactions that represent other processes, such as cellular respiration or nitrogen fixation, by checking the reactants and products involved.
5. Confirm that the correct reaction shows carbon dioxide and water as reactants, light as energy input, and glucose plus oxygen as products, matching the known photosynthesis equation.
