Answer:

Receptors are highly specific and only have high affinity for those ligands for whom they are specific.

Explanation:

Receptors are proteins that receive a stimulus or bind a ligand and mediate effects via receptor effector system.

Receptors are macromolecules that are highly specific.

The affinity between the ligand and the receptors is determind by the disassociation constant Kd.

The receptors produce maximun effect when an appropriate specific stimulus is present.

Different recptors types are present for different ligands.

For example, muscrinic receptors are specific for acetycholine and adrenergic receptors are specific for adrenaline/nor adrenaline.

It is important to know the specificity so that the body remains in a state of balance.

Answer:

Weight gain and depression are symptoms caused by imbalance of pituitary and adrenal glands and the cortisol hormone.

Explanation:

The pituitary gland is responsible for the overall functioning of the body since it produces a variety of hormones. It is very small in size and is also known as the 'master gland'. It is made of two parts- anterior pituitary gland and posterior pituitary gland. The pituitary gland and its functions are controlled by the hypothalamus.

The anterior pituitary secretes hormones which act on adrenal glands, thyroid, testes and ovaries. The hormones produced are TSH, Prolactin, Luitenizing Hormone, Cortisol, Testosterone, etc.

Cortisol is produced by the adrenal gland under the command of pituitary gland. Cortisol helps in regulating blood sugar, blood pressure and helps in reducing inflammation. Any imbalance of adrenal gland will cause an increase or decrease in the production of cortisol. The symptoms produced on the imbalance are:

Obesity in upper body
High blood pressure
Mood swings, depression and irritability
Acne and other skin problems.
