Question

Steps in non-cyclic photo-phosphorylation include passage of electrons along

• A. $\text{Chl a}\to \text{Cyt b6}\to \text{Cyt f}\to \text{PC}\to \text{PS I}\to \text{FRS}\to \text{FD}$
  
• B. $\text{PQ}\to \text{Cyt b6}\to \text{Cyt f}\to \text{PC}\to \text{PS I}\to \text{FRS}\to \text{FD}$
  
• C. $\text{FRS}\to \text{FD}\to \text{Cyt b6}\to \text{Cyt f}\to \text{PC}\to \text{Chl a}$
• D. $\text{Chl a}\to \text{PQ}\to \text{Cyt b6}\to \text{Cyt f}\to \text{PC}\to \text{PS I}\to \text{FRS}\to \text{FD}$
  

Answer 1

The correct option is B $\text{PQ}\to \text{Cyt b6}\to \text{Cyt f}\to \text{PC}\to \text{PS I}\to \text{FRS}\to \text{FD}$
