Answer:
In order for the sodium motive force to provide useful energy for the cell the organism must contain sodium ion gradient or potential across the membrane.
Explanation:
If the concentration of sodium is high in the inter membrane space than that of matrix then a sodium gradient is generated across the inner mitochondrial membrane.
The transport of sodium ions from inter membrane space to matrix through the sodium ion channel result in the generation of sodium motive force,that is used to provide energy to the cell.
Answer:
Arteries
Explanation:
There are three main types of blood vessels: veins, arteries, and capillaries. Arteries are the blood vessels that carry the oxygenated blood from the heart to various body parts. Veins pick the deoxygenated blood and deliver it to the heart to be oxygenated.
Arteries are the blood vessels with thick walls and no valves. Blood is pumped with higher pressure from the heart into arteries. The pulmonary artery is the only exception that carries deoxygenated blood from the right ventricle to the lungs for oxygenation.
