Question
Chapter 34, Problem 3RQ
Summary Introduction
To differentiate: the types of receptors located on the target cell surface and the nucleus along with examples of hormones that mediate action through each receptor type.
Introduction: Hormones are members of chemical signaling molecules, produced by endocrine glands, transported through the blood to distant target organs to regulate behavioral, physiology and

Under in vivo conditions, chronic treatment with a noncompetitive antagonist may lead to the up-regulation of the targeted receptor over time.
True
False
Cytokines are peptides that are generally made in advance by specific types of cells, stored in vesicles, and act as autocrine or paracrine factors.
True
False
Thyroid hormone is stored in an extracellular compartment.
True
False
Hormone receptor molecules are the key to understanding specific-ity of hormone action on target cells. Describe and distinguish be-tween receptors located on the cell surface and those located in the nucleus of target cells. Name two hormones whose action is medi-ated through each type of receptor.
One such laboratory study investigated the binding of a hormone to three different receptor proteins in the cell membrane. The data collected are shown in the table below
1) Provide a brief explanation as to why ligand binding toproteins must be a reversible process.
2) Calculate the dissociation constant (Kd) for the hormone binding to each of the three proteins.

Specify what class of hormones would be involved in this pathway.arrow_forwardPlace the following steps (showing how a steroid hormone changes the activities of its target cells) in order of what happens first, second, third, fourth, and last. Refer to image. The hormone-receptor complex enters the nucleus of the cell and binds to the DNA. The steroid hormone passes through the cell membrane. The hormone attaches to a receptor in the cytoplasm, forming a hormone-receptor complex. A gene in the DNA is activated, and transcription and translation take place. Proteins that alter the cell′s activities, such as enzymes, are made. 2. Place the following steps (showing how a hydrophilic hormone changes the activities of its target cells) in order of what happens first, second, third, and last. Refer to image. The activity of the target cell is changed by the final enzyme in the cascade. The second messenger activates or deactivates certain enzymes in a cascade fashion. A second messenger is activated. Hormone binds to a receptor protein.arrow_forward
- Explain the structure and location of the cellular receptor and describe in detail the mechanism of action of steroid hormones. Compare this to the structure and function of the insulin receptor. What properties are different between the ligands? What cellular responses occur to each as a result of receptor activation.
