The transfer of electrons from the primary electron acceptor of photosystem II to the P700 chlorophyll a molecules of photosyste
sesenic [268]

The photosystems are sets of chlorophyll molecules and other pigments and transmembrane proteins packed in the thylakoids, the transfer of electrons from the primary electron acceptor of photosystem II to the P700 chlorophyll a molecules of photosystem I is called photophosphorylation.

<h3>What is photophosphorylation?</h3>

It is the global process of transformation of the energy stored in the electron of the reactive center excited by light, in a pyrophosphate bond of an ADP molecule.

When a photon is absorbed by one of the pigments of photosystem II, it quickly bounces off the other molecules until it reaches chlorophyll a in the reaction center.

The electron, after leaving photosystem II, reaches the reaction center of photosystem I, where chlorophyll P700 is, the pigments absorb light and the electron reacquires a high level of energy.

Therefore, we can conclude that when this molecule absorbs light energy, an electron is thrown up to a higher energy level and transferred to another molecule, a primary electron acceptor.

What process involves the turning off or on the genetic information of a cell
JulijaS [17]

Differentiation is the process that involves the turning off or on the genetic information of a cell.

Differentiation is the process in which a young and immature cell changes into a specialized cell (a mature form with distinct function). Generic embryonic cells undergo differentiation to become specialized cells through the process of gene expression in which specific combination of genetic instructions are turned on (expressed) or off (repressed).
