Question

Select the true statements about eicosanoids. a. Eicosanoids are broken down within seconds to inactive residues. b. Arachidonic acid, a C20 fatty acid, is the precursor to eicosanoids. c. Eicosanoids are transported in the blood stream to their site of action. d. Eicosanoids are responsible for producing pain and fever. e. High concentrations of eicosanoids are necessary for effective action.

Answer 1

Answer: the true statements about eicosanoids includes options A,B,D,E

Explanation:

EICOSANOIDS are mostly produced from the precursor arachidonic acid, a C20 polyunsaturated fatty acid. They are broken down within seconds to inactive residues after synthesis.High concentrations of eicosanoids are necessary for effective action.The three major types of eicosanoids includes:

-prostaglandins,

- thromboxanes, and

- leukotrienes.

Depending on the above types mentioned, they play a role in inflammation, pain, fever promotion, blood pressure regulation, and blood clotting. They also influence the immune response and certain respiratory and reproductive processes.

However, eicosanoids are NOT transported in the blood stream to their site of action RATHER they exert their effects on the tissue where they are synthesized.
