What is the normal direction of calcium transport via the calcium pump?

out of the cell, against the concentration gradient.
The calcium pump moves calcium ions out of the cell - from the cytoplasm to the extracellular fluid. Because the calcium concentration is much higher outside the cell compared to the inside, this transport is against the calcium concentration gradient. Inside calcium concentrations often increase in response to hormones and nerve input. Calcium pumps are important in terminating these responses by returning calcium concentrations to resting levels.

The calcium pump in cell membranes is an example of what?
Active transport
What are three active transport pumps that function in biological systems?
Proton or hydrogen pump, which is necessary to maitain the normal pH of the stomach. Calcium pump, which is important in nerve and muscle function. And sodium-potassiumpump, which is integral in cellular metabolism.
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.
Through what type of proteins does active transport occur?
A carrier protein (as opposed to a channel protein). An example of a carrier protein is the Na+/K+ pump.
What type of active transport pump helps muscle cells contract?
the sodium potassium pump.

What is the energy source used by the calcium pump during its normal operation?
the hydrolysis of atp
What is the energy source used by the calcium pump durring its normal operation?
The hydrolysis of ATP

Extracellular fluid contains up to 10000 times more calcium than intracellular fluid and yet all cells continue to pump out even more calcium They could only do this by means of?
active transport
Does facilitated transport have a sodium potassium pump?
The sodium potassium pump requires ATP - i.e. it is involved in active transport, not facilitated transport.
How do you change a water pump 1999 Pontiac transport?
How to change a water pump on a 1997 Pontiac Transport
What does a ion exchange pump transport at the normal resting potential of a typical neuron?
3 intracellular sodium ions for 2 extracellular potassium ions
What is the transport of materials against a concentration gradient called?
The process of moving materials against a concentration gradient is called active transport. Active transport generally uses a protein pump to move molecules from an area of low concentration to an area of high concentration; in order to perform an active transport, the cell must use some of its energy to initiate the reaction.
What type of transport molecule transports the solute and the co-transported solute in the opposite direction?
antiport: transports 2 solutes in opposite directions (example: Na/K pump)
Which pump transports ions against their concentration?
active transport pump
