Answer:

The correct answer is NADPH.

Photo-system I absorbs maximum photons at the wavelength of 700 nm.

It uses this energy to transfer the electron (received from photo-system II) to NADP⁺ to reduce it to NADPH.

Once, the reaction centre of PS I or P₇₀₀ gets excited, it transfer the high energy electron to the ferrodoxin (Fd) via cluster of iron and sulphur protein (4Fe-4S).

Reduced ferrodoxin then transfer the electron to NADP⁺ to reduce it to NADPH with the help of flavoprotein (ferrodoxin-NADP⁺ reductase).

NADPH is then used in Calvin cycle or light-independent phase of the photosynthesis in order to fix carbon to produce sugar or food.

Does a moving magnetic field creat a megnetic field
faust18 [17]

Answer:

Same is true for the magnet. Changing your reference frame to that of the magnet will make the electric field disappear.
