Question:
Excitation of chlorophyll in light is
Excitation of chlorophyll in light is
Updated On: Nov 4, 2024
- Endergonic reaction
- Photochemical reaction
- Photo-oxidation reaction
- Thermochemical reaction
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
An excited chlorophyll loses electron. Loss of electron is termed oxidation. As this oxidation occurs under the effect of light hence excitation of electron is termed photo-oxidation (photos-light)

Photosynthesis in Higher Plants
Processes Of Photosynthesis in Higher Plants:
Photosynthesis in higher plants involves the following processes:
- Light Reaction
- Dark Reaction
Light Reaction:
- This phenomenon occurs in the presence of light.
- The pigment absorbs light and produces energy in the form of ATP.
- The process involves- absorption of light, water splitting, the release of oxygen, and formation of ATP and NADPH.
Dark Reaction:
This process occurs in the absence of light in the stroma of the chloroplasts. The following cycles are involved in the process:
- Calvin Cycle (C3 Cycle)
- C4 Cycle (Hatch and Slack Pathway)
