<h2>c) option is correct</h2>

Explanation:

Melanin causes skin pigmentation, lowers the skin's ability to make vitamin D in response to sunlight exposure and some studies show that older adults with darker skin are at high risk of vitamin D deficiency

If there is lighter skin tones of people, it implies that the amount of Vitamin D is more in those people and skin of those people have the ability to process vitamin D from the sun

A transmembrane protein has the following properties: it has two binding sites, one for solute A and one for solute B. The prote
Usimov [2.4K]

Answer:

The protein is a symport protein.

Explanation:

Transport proteins are proteins which are involved in the transport of solutes across the cell membrane. The binding of the solute to be transported across the membrane causes a conformational change in the shape of the protein, thereby moving the molecule to the side of nthe membrane it is to be transported. The difference in the concentration of the solute across the membrane known as concentration gradient is mainly responsible for the transport of molecules by the transport proteins.

There are three types of transport proteins: uniport, symport and antiport transport proteins.

Uniporters are involved in moving only one molecule across a membrane

Symporters are involved in moving two or more molecule across a membrane in the same direction.

Antiporters are involved in moving two or more molecule across a membrane in opposite directions.

From the description of the transport protein in the question, both solutes A and B are moved across the membrane simultaneously in the same direction. Therefore, the protein is a symport protein.
