Question

hormones aur vyauhar pr vistrut lekh​

Answer 1

Answer:

The term hormone refers to any substance in an organism that carries a signal to generate some sort of alteration at the cellular levels. The hormones secreted by the endocrine glands represent one group of hormones that arise in one tissue, or gland and travel a considerable distance through the circulation to reach the target cell expressing cognate receptors.Paracrine hormones arise from a cell and travel a relatively short distance to interact with their cognate receptors on other neighbouring cells. Autocrine hormones are produced by the same cell that functions as the target for that particular hormone. Hormones regulate specific target tissues in the body and not all cells. Molecular components of the cells, the receptors provide specificity to the hormone-cell interaction.

Molecular components of the cells, the receptors provide specificity to the hormone-cell interaction.The concept of receptors originated in the twentieth century with the work of Langley (1906). Receptors may be components of the plasma membrane or they may by cytosolic or nuclear components. Receptors provide a medium through which the hormone initially interacts with the cell.

Receptors provide a medium through which the hormone initially interacts with the cell.If each type of cell did not possess specific type of hormone receptors, all cells respond to the chemical messengers. If all cells respond to a single hormone, it will result in uncoordinated muscle contraction and relaxation, and uncontrolled secretion of numerous cellular products, such as enzymes and hormones.
