CRITICAL THINKING
HUMAN ANATOMY
Before an international cycling competition, the participants must undergo doping tests. Doping
refers to the use of chemical substances to enhance athletic performance. Often, the substances in question are synthetic versions of hormones.
Substances that are measured in urine are anabolic steroids. They are synthetic derivatives of
the hormone testosterone.
Anabolic steroids are on the International Olympic Committee’s list of banned substances. Use of anabolic steroids by an athlete has been linked to severe diseases of the heart.
In one to two paragraphs, address the following:
1. Explain why synthetic analogs of testosterone are labeled as anabolic steroids by referencing
the chemical structure of the compounds.
2. Explain why anabolic steroids are used by athletes to enhance their performance, providing
specific examples.
3. Describe the cause of the side effect of anabolic steroids usage described in the scenario
