Explanation / Answer

1.Point first is correct.

acetylcholine acts as a signal molecule for the cell. and the receptor for these molecule are nicotinic receptors so we can say the order of the names are incorrect.

the correct order is acetylcholine bands with the nicotinic receptors and leads to opening of chemically gated channels of the cell.

2. This is correct

Sodum ions are responsible for the release of Calcium from the ER. After the release of ER troponin interacts with tropomyosin which is unit of myosin and then leads to interaction with actin and myosin.

3. incorrect order.

signal molecules binds with the nicotinic receptors and then leads to sodium influx to the cell. After the influx of spdium ipns chemically gated channels will open.

4. incorrect order.

Somatic motor neuron transfers the tubules to the motor end plate.

5. incorrect order.

Troponin interact with actin and myosin protein for muscle contraction.

6.

this order is correct as i mentioned about that acetylcholine molecules binds to the nicotinic receptors and then leads to opening of chemically gated channels.

7. incorrect

when acetylcholine binds to the nicotinic receptors then leads to the influx of sodium by Sodium channels opening and then leads to change in voltage.

change in voltage leads to opening of voltage gated channels.

8 . orders is correct.

a vesicle moves at the end of motor flat and then transfer the terminal cisternae.

9. order is incorrect.

the correct order of all the Sequencing is depend upon the one pathway which is mentioned below: first of all aa signalling molecule which is acetylcholine is released by a cell and transferred to the another cell which have nicotinic receptors. these acetylcholine molecules binds to the nicotinic receptors and then leads to opening of sodium channels. the entry of sodium ions inside the cell leads to change in the chemical concentration of sel the entry of sodium ions inside the cell leads to change in the chemical concentration of cell. this change chemical concentration leads to opening of chemical gated channels.
