Pigments of PS I occurs in
A. Appressed part of granal thylakoids
B. Stromal thylakoids and nonappressed parts of granal thylakoids
C. Both appressed and nonappressed parts of granal thylakoids
D. Stroma
Answer: Option B
Solution (By Examveda Team)
Pigments of PS I occurs in Stromal thylakoids and non appressed parts of granal thylakoids.Photosystem I and photosystem II are the two multi-protein complexes that contain the pigments necessary to harvest photons and use light energy to catalyze the primary photosynthetic endergonic reactions producing high-energy compounds.
The PSI is located in the stroma lamella of the thylakoid while the PSII is in the stacked grana domain.
