Question

In light reaction, plastocyanin facilitates the transfer of electrons from:

• A. ${\text{PS I to NADP}}^{+}$
• B. $\text{PS I to ATP synthase}$
• C. $\text{Cyt b}{}_6\text{f complex to PS I}$
• D. $\text{PS II to cyt b}{}_6\text{f complex}$

Answer 1

The correct option is C $\text{Cyt b}{}_6\text{f complex to PS I}$

PQ facilitates the transfer of electrons from PS II to cyt b${}_6$f and PC from cyt b${}_6$f to PS I. PS II first transfers the electrons to pheophytin.
