cupoosta [38]3 years ago
3 0

Answer:

Stimulate an immune response

Explanation:

The vaccine is a preparation that contains a weakened or killed form of microorganism (or part of them) that stimulates the immune system to produce memory antibodies to recognize that microorganism in the future. After the body produces the memory antibodies, if a person is in contact with that microorganism the body recognized them as “strange” and the body response to killing them is faster before the infection. In some cases is necessary to apply various doses of the vaccine in a certain time to maintain the memory antibodies.

Epinephrine has to cross the cell membrane to bind to its receptor in the cytoplasm. True or False
Vinil7 [7]

Answer:

The statement is false.

Explanation:

Epinephrine (also known as adrenaline) is a hormone and a neurotransmitter produced by the adrenal glands, it helps to regulate cellular energy metabolism and increases the heart rate.

Epinephrine adheres to certain receptors that are exposed on the surface of a large number of body cells. This receptor, called beta-adrenergic, is a receptor that is embedded in the plasma membranes of these cells. Adrenaline does not penetrate the cell, instead, joining for a short period of time to its receptor, induces it to release biochemical signals to the cytoplasm of cells. This steric change, affects the configuration of the cytoplasmic domain of the protein, this is the "link" of the receptor that protrudes in the cytoplasm.
