Answer is: active transport.
In active transport<span> because energy is required to move the sodium and potassium ions against the concentration gradient. There is two type of active transport:
1) </span>Primary active transport directly
uses metabolic energy (adenosine triphosphate- ATP) to transport molecules
across a membrane.
2) In secondary active transport (coupled
transport) there is no direct coupling of ATP, energy derived from
the pumping of protons across a cell membrane.
The process living creatures go through to break down sugars and turn them into ATP is called Cellular Respiration.
Answer:
B) non oxygen blood (aka deoxygenated blood)
