7 0


The answer is B.

An inflammatory response is a nonspecific immune response. It is defined as a reaction of the body to injury or destruction of tissues and takes place in the following steps:

1. Tissue damage caused by injury or bacterial infection is detected.

2. Chemotactic factors and vasodilators are released.

3. increased capillary permeability and  increased blood flow to the area occurs.

4. Migration of phagocytes to the site of infection rapidly occurs.

5. Special serum proteins and phagocytes attack and destroy bacteria.

6. Inflammation subsides once the invading pathogen is destroyed.

kogti [31]

Answer:

The correct answer is option (b) "addition of a drug that prevents the α subunit from exchanging GDP for GTP".

Explanation:

The G protein is a name given to a family of proteins that act as a switch in diverse cellular processes, transmitting signals from outside to inside of the cells. When a G protein receptor is activated by a neurotransmitter such as dopamine, the alpha subunit exchanges its GDP for a GTP and disassociates G-protein itself. An addition of a drug that prevents this action would prevent  G protein disassociation, which would enhance the effect of stimulating G protein that acetylcholine does.

The alpha and beta receptors are known as _________ receptors and are found at the ________ of the ________ division.
Law Incorporation [45]

Answer:

Adrenergic/effector/sympathetic

Explanation:

The two main divisions of autonomic nervous system are sympathetic nervous system and para sympathetic nervous system. This nervous system controls the involuntary actions of the body.

Adrenergic receptors are included in the G protein coupled receptors. Alpha and beat receptors are adrenergic receptors. These receptors are present on the effector molecule. Alpha and beta receptors are important during fight and flight response and are included in the sympathetic nervous system.

Thus, the correct answer is option (e).
