What occurs during a single cycle of the sodium-potassium exchange pump?
Three sodium ions are moved out of the cell for every ATP hydrolyzed by the pump. At the same time, two potassium ions are moved into the cell.

How are Excess calcium and potassium are moved between interstitial fluids and blood?
Osmosis
What types of molecules are moved in osmosis?
osmosis is the diffusion of particles through a semi-permiable membrane
Form a hypothesis that can explain this observation Waves A and B travel away from Earth through Earth's atmosphere Wave A continues on into space but wave B does not?
they moved the oppsite direction
In a sodium-potassium pump what molecules are moved and where are they moved to?
In a sodium-potassium pump a carrier protein uses ATP in Active transport. The sodium ions are transported out of the cells and the potassium ions are transported into the cell.

Name two substances which are moved by active transport through membranes?
Sodium and Potassium. There is something called a sodium-potassium pump which transports 3 ions of Na+ out of the cell and 2 ions of K+ into the cell. This is facilitated by the breakdown of ATP to provide energy.
What is moved by active transport?
Molecules are moved by active transport.
What kind of molecules are moved in active transport?
Active transport requires energy, unlike passive transport. The carrier proteins in active transport act as a "pump" ( fueled by ATP) to carry/attach themselfves to useful proteins for the cell.
How are the sodium ions moved out of the neuron?
by "sodium pump", a process involving active transport
How molecules moved?
Molecules usually move from high concentration to lower concentrations.
How does the sodium and potassium pump act to maintain the resting membrane potential?
Primary active transport is the process in which ions are moved across cell membranes against the electrochemical gradient using energy supplied directly be ATP. The action of the sodium-potassium pump is an important example of primary active transport.Secondary active transport is indirectly driven by primary transport. In the sodium-potassium pump, by pumping against the gradient, energy is stored in the ion gradient. Then, just as water pumped uphill can do the work as it flows back down, (think water wheel or turbine), a substance pumped across the membrane can do work as it leaks back, propelled downhill along the concentration gradient.
Are valence electrons held loosely by the atom?
Assuming you are talking about the electrons in their shells (not the displaced ones):It depends on the distance of those electrons from the nucleus. For example electron in the outer shell of potassium (K) is further away form the nucleus than electron in the outer shell of sodium (Na).It means that potassium can lose this electron in outer shell easier than sodium does, and therefore is more reactive than sodium.
If the foot is abducted which direction is it moved in?
