Question

Which of these options is not a mechanism to control the opening and closing of ion

Answer 1

ATP binding (ATP gated) IS NOT a mechanism to control the opening and closing of ion channels (Option a).

ATP-gated channels are membrane channel proteins that open in response to binding ATP.

These channels require energy in the form of ATP to open and thus allow the passage of ions/molecules across biological membranes.

For example, the P2X7 receptor is an ATP-gated channel that mediates apoptosis (programmed cell death) of immune cells.

In conclusion, ATP binding (ATP gated) IS NOT a mechanism to control the opening and closing of ion channels (Option a).

Answer 2

Answer:

D) ATP binding (ATP gated)

Explanation:

There are three types of ion gated channel regulated by ligand binding, change in membrane potential and distortion of the cell membrane...

So the answer is ATP Binding( ATP gated) is not a mechanism to control opening and closing of Ion channels.
