In spite of this, cyclic electron flow is able to compete efficiently with PSI across a range of conditions. In dark-adapted leaves, the efficiency of cyclic relative to linear flow induced by far-red light is increased, implying that the limiting step of cyclic flow lies in the re-injection of electrons into the electron transport chain.
How does cyclic electron flow differ from linear electron flow (2)? 1. no NADPH is produced by cyclic electron flow 2. no O2 is produced by cyclic electron flow. ...

The production of oxygen and NADPH take place in non-cyclic electron flow and the system could switch to cyclic flow upon accumulation of oxygen and NADPH ... 1 and 2 cooperate to achieve a linear ...
Linear electron flow is the electrons that pass through the two photosystems from water to NADP+. Cyclic electron flow are the electrons excited from P700 in PSI are passed from Fd to the cytochrome complex and back to P700.
Cyclic vs. Non-cyclic Electron Flow . Under certain conditions, the photoexcited electrons take an alternative path called cyclic electron flow, which uses photosystem I (P700) but not photosystem II (P680). This process produces no NADPH and no O 2, but it does make ATP. This is called cyclic photophosphorylation.
Cyclic electron flow avoids both photosystem II and the donation of electrons to NADP +. Electrons instead are passed from photosystem I to an electron transport chain, resulting in proton pumping, and then returned to reduce photosystem I, returning that photosystem to its ground state. Also can be described as a cyclic photophosphorylation.
Most plants go through either non-cyclic electron flow or cyclic electron flow in order to dictate the products of light reactions during photosynthesis. During cyclic electron flow, the electrons that move stop when they reach ferrodoxin.
Whereas linear flow from water to NADP + is commonly used to explain the function of the light-dependent reactions of photosynthesis, the role of cyclic flow is less clear. In higher plants cyclic ...
Best Answer: If you are talking about photosynthesis, the products of linear electron flow are ATP, oxygen (from water) and NADPH (from NADP+). Cyclic electron flow just produces ATP
