Question

Number of ATP molecules and ${\mathrm{NaDPH}}_2$ molecules in cyclic photophosphorylation.

• A. $1$ and $1$
• B. $1$ and $2$
• C. $2$ and $1$
• D. $2$ and $0$

Answer 1

The correct option is D

$2$ and $0$

The correct option is D.

Explanation of the correct option:

1. Photosynthesis is the process by which green plants manufacture carbohydrates from carbon dioxide and water in the presence of sunlight and chlorophyll.
2. In the light-dependent phase of photosynthesis, ATP and ${\mathrm{NaDPH}}_2$ is produced as the end product of photolysis.
3. The addition of phosphate in the presence of light which results in the synthesis of ATP is known as photophosphorylation.
4. In cyclic photophosphorylation, only 2 ATP molecules are produced.

Final Answer: Number of ATP molecules and ${\mathrm{NaDPH}}_2$ molecules in cyclic photophosphorylation is $2$ and $0$
