- The type of transport represented is active transport.
- Energy is being used in the form of ATP.
- Movement is occurring against the concentration gradient.
- The interior of the cell is labeled as the cytoplasm.
- The transport proteins are labeled as carrier proteins.
- The substance being moved is labeled as ions.
- This type of active transport is called the sodium-potassium pump.
- The pump uses ATP to move ions against the concentration gradient.
- The protein that is used to pump the ions through is called a transmembrane (integral) protein.
- It changes its shape to move the ions across the cell membrane.
- The carrier proteins are labeled as integral membrane proteins.
- The ions are labeled as sodium and potassium ions.
- A solution is a fluid in which a substance is dissolved.
- A solute is a substance dissolved in a solvent.
- A solvent is a combination of solute and solvent.
- The process by which water diffuses across a membrane is called osmosis.
- Solution B is hypertonic to Solution A. This is because Solution B has a greater concentration of solute than Solution A. Solution C has no solute dissolved in it, therefore it is hypotonic to both Solutions A and B.
