Question

How many photons does it take to fully reduce one molecule of NADP+ to NADPH?

a. 1

b. 2

c. 4

d. 8

Short answer

There are $2$protons does it take to fully reduce one molecule. Option (b) is correct answer

Step-by-step solution

Incorrect (a), (c), and (d)

In phloem, the chromophore is a glycoprotein complex incorporated in the chloroplast. There still are two types of photoreceptors: photosystem I and photosystem II.

When a ray touches an electrode molecule, resulting from the rapid. Photosystems like as chlorophyll or other carotenoids get linked in antenna proteins.

Antenna molecules circle the reaction core. At the active site, photochemistry did take place.

The major electro catalyst is a constituent of photosystem II it aids in the passage of electrons to photosystem I.

Correct (b)

An electrons of a dye molecule is generated in the PSII site of the ribosome when a signal is detected. This excited state is unstable but is moved to another receptor, causing a massive. PSII transmits an electron to cytochrome $b6$, that is then passed to PSI. Each photon from excite the molecule still further. ${\mathrm{NADP}}^{+}$(final electron acceptor) inevitably catches the ion, that is then oxidized to NADPH.
