Q
A scientist investigated the effect of inhibitors on neurones. She added a respiratory
inhibitor to a neurone. The resting potential of the neurone changed from –70 mV to 0 mV.
Explain why.
A
less ATP produced;
less active transport
3. Electrochemical gradient not maintained
2
Q
Damage to the myelin sheaths of neurones can lead to problems controlling the contraction
of muscles.
Suggest one reason why.
A
Action potentials travel more slowly
2. So delay in muscle contraction
