When a person is anxious or fearful, the autonomic nervous system shunts blood away from peripheral veins to the core of the body - TRUE
- Sympathetic stimulation of blood vessels causes arteries and arterioles (resistance vessels) to constrict, increasing vascular resistance and reducing distal blood flow.
- The increased vascular resistance that results from this across the body raises arterial pressure.
- When our bodies shift into superman mode, the second signal is transmitted to the hypothalamus, where it activates our autonomic nerve system,
- which is in charge of the fight-or-flight impulse.
- Our bodies receive an adrenaline boost as well as an increase in heart rate and blood pressure. When you are afraid, you get that rush.

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.
