What happens in the dark reaction of photosynthesis?
What happens in the dark reaction of photosynthesis?
Show Hint
Dark reaction fixes CO\textsubscript{2} and synthesizes PGAL for sugar formation.
Updated On: May 19, 2025
- Formation of ATP
- Evolution of Oxygen
- Evolution of Hydrogen
- PGAL synthesis
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
The dark reaction, also known as the Calvin cycle, occurs in the stroma of chloroplasts and does not require light directly. It synthesizes PGAL (phosphoglyceraldehyde), a three-carbon sugar, by fixing atmospheric CO\textsubscript{2} using ATP and NADPH produced during the light reactions.
- ATP formation and oxygen evolution occur during light reactions.
- Hydrogen evolution is not part of photosynthesis.
- ATP formation and oxygen evolution occur during light reactions.
- Hydrogen evolution is not part of photosynthesis.
