These processes occurs during repolarization of nerve fibre
(i) Open `Na^(+)`channel (ii) Closed `Na^(+)` channel
(iii) Closed `K^(+)` channel (iv) Open `K^(+)` channel

Classify the following curves as (i) Open or (ii) Closed.

Identify the region where all Na^(+) channels are reactivated but closed and all K^(+) channels are closed

How many gate(s) is/are present in each voltage gated Na^(+) channel?

Classify the following curves as ( i ) Open or (ii) Closed.

Depolarisation of neuron is caused due to 1) Opening of K + leak channels 2) Opening of voltage gated K + channels 3) Opening of voltage gated N a + channels 4) Both (2) & (3)

Classify the following curves as (i) open or (ii) closed:

During resting state, the gate of K^(+) channel is

Ionic channels that remain open all time
