general questions Flashcards
1
Q
why is the transmission of impulses faster along a myelinated axon than a non myelinated axon
A
-provides insulation along the axon
- means that electrical impulses( action potential) can jump from one node of randiver to another
-requiring less ATP
2
Q
-a scientist added a respiratory inhibitor . The resting potential went from -70 to 0 why
A
- ATP cant be produced as respiration cant happen
-sodium/ potassium pump work using atp
-so 3 sodium ions cant be actively transported out
3
Q
what does lipid soluble mean
A
means that its uncharged
and can diffuse through lipid bilayer
sodium and potassium are polar ions so they cant diffuse through as they’re charged
