Give difference between cyclic and noncyclic photophosphorylation

Difference between cyclic and noncyclic photophosphorylation

 

Cyclic photophosphorylation Non – cyclic photophosphorylation
  • Involves cyclic pathway of electrons.

 

  • Photo system 1 is the first electron donor.
  • Photo system 1 is the last electron acceptor
  • Product is ATP only

 

 

  • Only photo system 1 is involved
  • Involves non –cyclic pathway of elections.
  • Water is the first electron donor

 

  • NADP is the last electron acceptor

 

  • Products are ATP, reduced NADP and oxygen.

 

  • Bothe photo system 1 and 11 are involved.
