Question

Quizplus · Accepted Answer

Hormones are the powerful chemical substances secreted by endocrine glands that travel through the bloodstream and bring about changes in the body during puberty. Enzymes are not secreted by endocrine glands and do not play a significant role in puberty. Neurotransmitters act on the nervous system, not the endocrine system, and do not directly contribute to pubertal changes. Serums are not an accurate term to describe hormones or their function.
