Question

What is the chemical nature of the receptor?

Answer 1

Receptors:

1. Receptors are made up of protein that transmits signals to the cell.
2. Receptors can be intracellular receptors and cell surface receptors.
3. Intracellular receptors are in the interior of the cell i.e, in the cytoplasm or nucleus.
4. Cell surface receptors are present on the cell surface in the plasma membrane.

Chemical nature of the receptor:

1. There are three ways the receptor's action can be seen-

1. Relaying the signal
2. Amplification
3. Integration

2. The receptor receives chemical signals from outside the cell.

3. When signaling molecules bind to a receptor, the cell then either divide, die, or allow specific substances to enter or exit the cell.

4. Receptors are proteins which are embedded in either the cell’s plasma membrane, in the cytoplasm, or in the nucleus , to which specific signalling molecules( ligand) may attach.
