Mechanism of Hormone Action – Notes CBSE Class 11
Mechanisms of Hormone Action are seen in the protein hormones such as Insulin, Adrenaline, TSH, and so on. These protein hormones are water soluble and they cannot pass through the cell membrane as it is made up of a lipid layer therefore this is known as a fixed membrane receptor mechanism whereas steroid hormones are made up of fats and are insoluble in water. These receptors are intracellular and can float in the cytoplasm on the nuclear membrane or inside the cell and due to this they are mobile receptor mechanisms.
