Which of the followings is the synonymous for the Blackman's reaction in photosynthesis?
Show Hint
Dark reaction: Calvin cycle, CO2 fixation, Blackman's reaction.
Light reaction: Hill reaction, photo-chemical reaction.
Blackman's reaction occurs in the stroma of chloroplasts.
Light reaction: Hill reaction, photo-chemical reaction.

Updated On: Aug 25, 2026
- Light reaction
- Photo-chemical reaction
- Hill reaction
- Dark reaction
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Photosynthesis has two stages: light reaction and dark reaction.
Step 2: Detailed Explanation:
Blackman's reaction is another name for the dark reaction (Calvin cycle) of photosynthesis.
Blackman (1905) studied the effect of temperature and CO2 concentration on photosynthesis.
He proposed that photosynthesis has:
- Light reaction (dependent on light intensity).
- Dark reaction (dependent on temperature and CO2, not directly light).
Other terms:
- Light reaction (A): Also called Hill reaction (C) or photo-chemical reaction (B).
- Dark reaction (D): Also called Blackman's reaction or Calvin cycle.
Thus, Blackman's reaction is synonymous with dark reaction.
Step 3: Final Answer:
Thus, Blackman's reaction is synonymous with the dark reaction.
