Some of our neurons (cells of our nervous system) have atp-gated calcium (ca+2) channels in both their plasma membrane and nuclear envelope. (tricky
a. true
b. false

The given statement is true.

Explanation:

Some of the neurons possess ATP-gated calcium channels in both their nuclear envelope and plasma membrane. The majority of the ion channels are ligand-gated and stays in their position, which shows that they do not move from one membrane to another.  

However, the ATP gated calcium channels have been located in both the nuclear envelopes of some of the neurons and plasma membrane, which signifies that the channel may socialize between the two compartments.  

a time line cause it goes from 685 to 978

option a and d is the correct answer

i hope this u
