Tyrosine Steroid hormones Catecholamines Peptide hormones This type of hormone is derived from proteins: Question 5 2 / 2 pts Growth hormone Question 6 2 / 2 pts Explain the concept of negative feedback and how it helps to maintain homeostasis. Your Answer: the action of a hormone decreasing the production of that hormone as a regulatory process 1- The effect or increased level of the hormone acts to shut down the continued release of the hormone. 2- The brain is constantly monitoring hormone levels to keep levels within a certain range or set-point (homeostasis). Negative feedback is a way of “turning off” hormone production when the desired level is achieved 8/20/22, 3:52 PM 5/15 Correctt!
