Question

In some cells _________ is responsible for transmission of impulse A) Plasma membrane C) SER B) RER D) ER

Answer 1

it's plasma membrane

option a

Answer 2

Answer:

A) Plasma membrane

Explanation:

• in neuron cells the axonal membrane conducts impulse and transmits it to other neurons for to muscles for nervous stimulation in our body.
• SER is smooth endoplasmic reticulum which is mainly involved in lipids and sterol synthesis.
• RER is rough endoplasmic reticulum which is called rough due to the presence of ribosomes on its surface which are involved in protein synthesis.
• ER is endoplasmic reticulum which is of two types SER and RER as discussed above.
• ER is an organelle and it present inside the cell and does not involve any impulse transmission.

so answer is plasma membrane
