Pigment acting as a reaction centre during photosynthesis is
A. Carotene
B. Phytochrome
C. P700
D. Cytochrome
Answer: Option C
Solution(By Examveda Team)
Pigment acting as a reaction centre during photosynthesis is P700.The process always begins when energy from light is absorbed by proteins called reaction centers that contain green chlorophyll (and other coloured) pigments/chromophores.
The excited electrons lost from the reaction center (P700) of photosystem I are replaced by transfer from plastocyanin, whose electrons come from electron transport through photosystem II.
P700 absorbance and gas exchange measurements reveal detailed information about e.g. the photosystems, quantum efficiency and the CO2 assimilation rates.
