Passive, random movement of uncharged particles from regions of high to regions of low concentration.
Cell mediated movement from regions of high concentration to regions of low concentration for larger particles; requires no extra energy, carrier protein changes spontaneously
Movement of a solvent, through a semi-permeable membrane to create an equal concentration of solute molecules.
Uses energy from to transport material against a gradient; that can be concentration, pressure, osmotic or voltage
What is the sodium potassium pump?
Primary active pump found in the sarcoplasmic reticulum (SR) of muscle cells. Moves ions back in to SR after contraction.
Movement of one type of molecule is brought about due to a change in shape of the carrier protein caused by another molecule being transported.
What is a uniporter?
What are symporters?
What is an antiporter?
Process which transports particles into the cell by trapping them in vesicles produced from the cell membrane.
Process which transports particles out of the cell in to the ECF with using vesicles produced by the cell membrane.
The name given to the difference in voltage between the inside of the cell and the outside of the cell, across the cell membrane.
The inside of the cell membrane generally has a more positive, or negative charge?
The outside of the cell membrane generally has a more positive, or negative charge?
How many mV is the membrane potential of cardiac cells?
How many mV is the membrane potential of red blood cells?
