Question

Where is the receptor located in the body and what is its function? How many receptors are present in the human body?

Answer 1

Receptors are the sensing molecules or factors which communicate the sign from a ligand to the mobile to elicit specific physiological trade. These receptors are positioned within the cells, tissues and help to manipulate almost all the frame organs. Receptors are biological transducers that convert electricity from both external and inner environments into electrical impulses.

Complete answer:
Receptors may be massed together to form a feeling organ, inclusive of the eye or ear, or they may be scattered, as are those of the skin and viscera. All receptors file two features of stimulation, its depth and its vicinity.
Intensity is signalled with the aid of the frequency of nerve impulse discharge of a neuron and additionally by using the number of afferent nerves reporting the stimulation. As the electricity of a stimulus will increase, the fee of change in the electrical capacity of the receptor increases, and the frequency of nerve impulse era likewise increases.

There are four primary sorts of receptors like
-Ligand-gated ion channel receptors
-G-protein coupled receptors
-Kinase-related receptors
-Nuclear receptors

Based on their area within the frame:
-Cell floor receptors
-Cytoplasmic receptors
-Intra-Nuclear receptors
-Floating receptors

Based on the physiological impact inside the frame
-Pharmacological receptors
-Silent receptors
-Orphan receptors
-Synaptic receptors.

These receptors are positioned in the cells, tissues and help to manipulate all maximum all of the frame organs. The ligand is the one that binds to the receptor and brings in conformational adjustments to provide a particular effect at the frame’s body structure.

Note: Most receptors have endogenous ligands or biomolecules which can trigger a reaction. Steady-kingdom receptors, as an instance, generate impulses as long as a particular country such as temperature stays constant. Their action involves enzymatic activation by the process phosphorylation. Then, there may be a gene transcription and protein synthesis to provide the impact.
