Proteins that assist in the movement of substances across can be classified into two types which are:
<h3>What are Proteins?</h3>
These are biological molecule which consists of amino acid sequences and are involved in metabolic activities in the body.
They are also found in cells and help in the selective movement of molecules in and out of the cell.

Answer:
(B) The concentration of ATP in cells is generally much lower than that of AMP.
Explanation:
AMP is 5’-adenylic acid or adenosine monophosphate. It has only one phosphate group attached to the sugar as compared to three phosphate groups of ATP. In general, cells have a much lower concentration of AMP than ATP. ATP is found in much higher concentration in cells than the AMP since ATP serves as energy currency for the cells while AMP is involved in relatively few metabolic pathways.

The answer should be C, the heart and the blood vessels.
The heart acts as a pump in the circulatory system. It pumps blood to organs and tissues all around the body. Meanwhile, the blood vessels (arteries, veins, and capillaries) help transport the blood to tissue and cells and back to the heart. Each type of blood vessel has their own function.
The brain is not involved in this system, as the whole circulation process does not require any us to make any decision.
In addition, there's also one structure that is in the blood vessels, but technically not another item for the circulatory system. That's valves, they are like flaps that ensure blood flowing in one wag direction and to prevent the back flow of blood.
So, the answer is C.
