Cyclic
Photophosphorylation
- Definition
- The synthesis of ATP during photosynthesis,
coupled to the cyclic electron transfer to and
from P700, involve in photosystem I, using a
series of electron carriers.

- Purpose
- to produce ATP faster
- Why?
- to produce 1 molecule of glucose, 18
ATP and 12 NADPH are required.
- not enough ATP are synthesized in
non-cyclic photophosphorylation
- not enough ATP are synthesized in
non-cyclic photophosphorylation
- to produce 1 molecule of glucose, 18
ATP and 12 NADPH are required.
- Why?
- to produce ATP faster
- Pathway
- What triggers it?
- accumulation of NADPH from
non-cyclic
photophosphorylation
- as result, switch from non cyclic
photophosphorylation to cyclic
photophosphorylation
- as result, switch from non cyclic
photophosphorylation to cyclic
