the resting membrane potential

Question 1

Resting membrane potential of cardiac muscle

Answer 1

-80

Question 2

Resting membrane potential of neurons

Answer 2

-70

Question 3

Resting membrane potential skeletal muscles

Answer 3

-90

Question 4

Resting membrane potential of smooth muscles

Answer 4

-50

Question 5

Membrane potential

Answer 5

Electrical potential voltage difference across the plasma membrane

Question 6

How do you measure the membrane potential

Answer 6

volt metre
the micro electrode is a fine glass pipette
the tip diameter is 1 µm
cell penetrate cell membrane
filled with the conducting solution

Question 7

Resting potential

Answer 7

Membrane potential is the electrical charge access across the membrane and is always expressed as the potential inside the cell relative to the extracellular solution

Question 8

Selected permeability of the cell membrane due to

Answer 8

Phospholipid bilayer

specific ion channels

Question 9

Ion channel properties

Answer 9

Selective
gated: the pore can be open or change by conformational change in the protein
rapid ion flow: boys down the electrochemical gradient

Question 10

How does the resting membrane potential arise

Answer 10

Membrane selected payable to potassium

When the chemical gradient for potassium and the electrical gradient for potassium are equilibrium there will be no net movement of potassium but there will be a negative membrane potential

Question 11

How to calculate the equilibrium potential

Answer 11

The nerst to equation
