ligand-gated ion channels motor end plate voltage-gated K\' channels In response

Question

ligand-gated ion channels motor end plate voltage-gated K' channels In response to acetylcholine binding, sodium ionsmove into the muscle fiber causing the membrane potential to rise. Acetyicholine diffuses across the synaptic cleft before binding to its receptor, which is located on the motor end plate voltagegated Ca channels An action potential reaches the axon terminal causing voltage-gated voltage-gated Na channels Stimulated by calcium ionsO, acetylcholine is released into the synaptsic cleft via exocytosiso exocytosis When the membrane potential reaches thresholoo an action potential spreads across the sarcolemma due to the opening of voltage-gated Na channelsO calcium ions sodium ions F7 4

Explanation / Answer

answer :

1) in response to acetylcholine binding calcium ions move into the muscle fibre causing the membrane potential to rise.

2) this answer is ligand gated ion channel acetylcholine is released into the synaptic cleft via exocytosis.

3) motor end plate

4) voltage gatedNa+ channels

5) stimulated by threshold and calcium ion

6) when the membrane potential reaches thresold an action

Potential spreads across the sarcolemma due to opening of voltage gated Na+ channels.
