Membrane channels

Answer 1

Belong to a class of transport proteins that form pores to allow the passage of small charge particles

Question 2

All channels move substance down where?

Answer 2

Question 3

Unlike career proteins

Answer 3

Channels interact very weakly and solutes the transport, allowing to move rapidly across the membrane

Question 4

Voltage gated channel

Answer 4

Response to change and membrane potential and are very vital and generating electrical impulse in nerve and cardiac cells

Question 5

Ligand gated ion

Answer 5

Channel opens in response to the binding of Ligand, such as a hormone or neurotransmitter
