Question

1) Which of these factors is inversely proportional to flux?

A---resistance

B---gradient

C---charge

D---current

2) The rate of flux for an ion such as Na+ will be determined by (select all that apply)

A---The difference in concentration of Na+ across the membrane

B---the electrical difference between the inside and outside of the cell

C---the water molecule concentration inside and outside the cell

3) If the membrane potential is at +45mV, what will you notice about the flux of Na+?

A---It will be from outside to inside and faster than at resting membrane potential

B----It will be from outside to inside and slower than at resting membrane potential

C---It will be from inside to outside and faster than at resting membrane potential

D----It will be from inside to outside and slower than at resting membrane potential

Explanation / Answer

generally what is flux? we know that flux is the flow of energy through surface of medium. in electronics, these are applied either in electric field or in the magnetic field. flux is depicted as lines in a plane in electric charge field or in the magnetic field. here, charge is inversely proportional to the flux, the rate of flux for an ion such as Na+ will be determined by the electrical difference between the inside and outside of the cell. if the membrane potential is at +45mV, what will you notice about the flux of Na+, it will be from outside to inside and slower than at resting membrane potential.
