The process through which excess of light energy is dissipated in photosynthesis is known as
-
- Quenching
- Scavenging
- Photolysis
- Photo-phosphorylation
Correct Option: A
Quenching is a process in which absorbed light energy is dissipated as heat and does not take part in photo-chemistry. The phenomenon involves quenching of chlorophyll a (Chla) fluorescence, which is induced under steady-state illumination.
