Question

Identify the correct photosynthetic equation.

• A. \(6CO_2+H_2O \xrightarrow{Light,\ Chlorophyll}CH_2O+H_2O+6O_2\)
• B. \(CO_2+H_2O \xrightarrow{Light,\ Chlorophyll}CH_2O+2H_2O+O_2\)
• C. \(6CO_2+6H_2O \xrightarrow{Light,\ Chlorophyll}C_6H_{12}O_6+6H_2O+6O_2\)
• D. \(6CO_2+12H_2O \xrightarrow{Light,\ Chlorophyll}C_6H_{12}O_6+6H_2O+6O_2\)

Answer 1

The Correct Option is D

1. Photosynthesis Equation:
The process of photosynthesis is the method by which plants convert carbon dioxide and water into glucose and oxygen, using light energy. The general chemical equation for photosynthesis is:

\[ 6\text{CO}_2 + 6\text{H}_2\text{O} \xrightarrow{\text{Light}, \text{Chlorophyll}} \text{C}_6\text{H}_12\text{O}_6 + 6\text{O}_2 \] This equation shows that six molecules of carbon dioxide and six molecules of water, in the presence of light and chlorophyll, produce one molecule of glucose and six molecules of oxygen.

2. Analyzing the Given Options:
Option (A): This equation is incorrect because the products are not glucose and oxygen. It shows the formation of water and oxygen, which is incorrect for photosynthesis.
Option (B): This equation is also incorrect. It suggests the formation of water and oxygen from carbon dioxide and water, which is not the process of photosynthesis.
Option (C): This equation is incorrect because it does not show the correct products (glucose).
Option (D): This equation is correct. It represents the proper photosynthetic reaction where glucose and oxygen are produced from carbon dioxide and water.

3. Conclusion:
The correct photosynthetic equation is shown in option (D).

Final Answer:
The correct answer is (D) \( 6\text{CO}_2 + 12\text{H}_2\text{O} \xrightarrow{\text{Light}, \text{Chlorophyll}} \text{C}_6\text{H}_12\text{O}_6 + 6\text{O}_2 \).
