Which of the following receptors responds to an electrical gradient across a membrane?
A
Ion Channel Receptors
B
G-Protein Coupled Receptors
C
Signal Coupled Receptors
D
Enzyme Coupled Receptors
Verified step by step guidance1
Understand the types of receptors: Ion channel receptors, G-protein coupled receptors, signal coupled receptors, and enzyme coupled receptors.
Ion channel receptors are a type of receptor that opens or closes in response to an electrical gradient across a membrane, allowing ions to pass through.
G-protein coupled receptors are involved in transmitting signals from outside the cell to the inside, but they do not directly respond to electrical gradients.
Signal coupled receptors and enzyme coupled receptors are involved in signal transduction pathways but are not directly activated by electrical gradients.
Identify that ion channel receptors are the ones that respond to changes in the electrical gradient across a membrane, allowing ions to flow in or out of the cell.
