A new hormone is discovered. Analysis suggests that it is synthesized on demand and has a long half-life in the bloodstream. It seems to activate gene transcription in its target cells, though no cell surface receptors can be identified. Which type of hormone is this most likely to be? A) Steroid hormone B) Catecholamine C) Thyroid hormone D) Peptide hormone

Which of the following is true about lipophilic hormones? a. They are freely soluble in the blood. b. They require a transport protein in the bloodstream. c. They cannot enter their target cells. d. They are rapidly deactivated after binding to their receptors.
In the endocrine system, it asks, "describe the two major mechanisms by which hormones bring about their effect on their target tissues?"I was thinking it was polar and non polar soluble because that's the major component when it comes to how cells react to their hormones, it determines how fast the reaction time.
Which of the following is NOT a trait of lipid-soluble hormones? A. They often need help of carrier proteins to circulate in the blood stream. B. They frequently activate signal transduction pathways that use second messengers. C. They easily diffuse through the phospholipid bilayers of target cells. D. They are typically modified lipids E. They normally leave secretory cells without using exocytosis
Is a hormone altered when it binds to a receptor? Is the receptor altered as a consequence of hormone binding? What are the forces that bind hormone to receptor?
What does the feedback loop for Vincent look like? Be sure to indicate all the hormones and glands involved in the feedback loop. Indicate whether the hormone levels are increasing or decreasing. Use arrows to indicate the direction of influence and label whether it is negative or positive feedback. Construct a feedback loop. To treat Vincent's condition the doctors removed a small part of the thyroid gland. After the surgery what were the thyroxin feedback loop look like now? Use the feedback loop generated for the first part of the question and modify it to demonstrate the change is stemming from the medical treatment.
