Which of the following statement is correct regarding doping?
I. EPO is a peptide hormone.
II. EPO is released from the kidneys.
Show answer & explanation
Correct answer: C
Explanation
EPO is a peptide hormone: Erythropoietin is a glycoprotein hormone, which is also classified as a peptide hormone due to its amino acid structure. In the context of doping, it is used by athletes to enhance the blood's oxygen-carrying capacity.
EPO is released by the kidneys: In the human body, EPO is primarily produced by specialized cells within the kidneys. When oxygen levels in the body drop, the kidneys secrete this hormone, which stimulates the bone marrow to produce more red blood cells (RBCs).
Both statements provided regarding doping and EPO are correct.
