The light-dependent reactions include an electron transport chain system that works in a very
mamaluj [8]

Explanation:

When the high energy electrons move from the reactive center, they are conveyed from one chain protein to another as the energy in the electrons is harnessed to pump H+ ions from the stroma into the lamellae. The electron will ultimately reduce NADP+ to NADPH and the electrons in the reactive center will be replaced by high energy electrons from the splitting of a water molecule in photolysis. The energy of the sun is used to split the water molecule. The high energy electrons then undergo the same cycle as the previous electrons and the cycle continues.

Eventually a proton-motive force is created across the lamellae membrane. This potential energy of the high H+ ion gradient is used by ATP synthase enzyme to phosphorylate ADPs to ATPs.

zzz [600]

Answer:

Mollusca Phylum

Gastropoda class

Explanation:

The Mollusca Phylum is one of the most noticeable phyla that includes a wide variety of forms.

The ancestral Mollusca used to habit the pre-cambric oceans. It was bilaterally symmetrical, with a well-defined head that had tentacles and ocellus. Its ventral surface was plane and muscular, shaping a reptant foot. The dorsal surface was protected with a convex and oval shell.

The Gastropoda class is the richest class among all mollusks. This class experienced a characteristic torsion in their shell. This twist also involved the visceral mass, the mantle, and the mantle cavity. But by the time that this torsion occurred, the shell had already experienced a turn into a coil shape, which was then followed by its torsion.

The typical gasteropod´s shell is a conical structure composed of several tubular spirals containing the individual´s visceral mass. The biggest spiral ends as an opening from which the head and the food protrude.
