A
It is a peptide hormone.
B
It is secreted by the pituitary gland.
C
It is responsible for the development of male secondary sexual characteristics.
D
It is primarily produced by the adrenal glands.
Verified step by step guidance1
Understand the nature of testosterone: Testosterone is a steroid hormone, not a peptide hormone. Peptide hormones are made of amino acids, whereas steroid hormones are derived from cholesterol.
Identify the source of testosterone production: Testosterone is primarily produced by the testes in males, with a smaller amount produced by the adrenal glands. It is not secreted by the pituitary gland.
Recognize the role of testosterone in the body: Testosterone is responsible for the development of male secondary sexual characteristics, such as increased muscle and bone mass, and the growth of body hair.
Differentiate between the glands involved: The pituitary gland secretes hormones that regulate other glands, including the testes, but it does not produce testosterone itself.
Conclude with the correct statement: Based on the information, the statement that testosterone is responsible for the development of male secondary sexual characteristics is true.
