Cyclic Photophosphorylation & Noncyclic Photophosphorylation, Phototrophy Flashcards | Quizlet, Cyclic Photophosphorylation & Noncyclic Photophosphorylation, Non-Cyclic Photophosphorylation: Only Photosystem I is involved. Both Photosystem I and II are involved. P700 is the active reaction centre. P680 is the active reaction centre. Electrons travel in a cyclic manner. Electrons travel in a non – cyclic manner. Electrons revert to Photosystem I: Electrons from Photosystem I are accepted by NADP.
Non-Cyclic Photophosphorylation . 1. Light is absorbed by each photosystem and excited electrons are emitted from P700 and P680. 2. These electrons are absorbed by electron acceptors and pass along a chain of carriers, leaving the photosystems positively charged. 3. P700 absorbs electrons from photosystem II.
Noncyclic photophosphorylation employs which photosystem (s)? … What is the fate of the NADPH molecules created during noncyclic photophosphorylation ? They are used in the Calvin-Benson cycle. Enzymes are important in living organisms because they _____.
Electron Transport Chain, Photosynthesis, Light-dependent Reactions, ATP synthase, Thylakoid
