The Electron Transport

Question

Statement A : Cyclic electron transport of photosynthesis takes place in both grana lamellae and stroma lamellae.
Statement B: PSI is present in both grana lamellae and stroma lamellae.

Easy

A

Both statements A and B are correct.
B

Statement A is correct and B is incorrect.
C

Both statements A and B are incorrect
D

Statement A is incorrect and B is correct.

Solution

Both grana lamellae and stroma lamellae have PSI. PSII is present only in grana lamellae. Hence, non-cyclic electron transport mainly takes place in grana lamellae and cyclic electron transport and phosphorylation predominantly takes place in stroma lamellae.
