- Identify the incorrect statement: O A. Steroid hormones, such as testosterone, are derived from cholesterol and regulate cell function by influencing transcription. O B. Melatonin is a hydrophobic steroid hormone synthesized by the pineal gland It regulates the circadian rhythm of the cell OC. Catecholamines are hydrophilic hormones synthesized from tyrosine. Therefore, membranes are barriers to them, and their receptors need to be on the extracellular surface. O D. Antidiuretic hormone is a peptide hormone that regulates fluid balance in the body O E. Thyroid hormone is a hydrophobic tyrosine derived hormone that regulates the metabolism,Which of the following pairs correctly describes an example of antagonistic hormones that regulate homeostasis? Question 14 options: thyroxine and parathyroid hormones regulate calcium balance progestins and estrogens control sexual differentiation epinephrine and norepinephrine regulate the fight-or-flight responses insulin and glucagon regulate blood glucose levelsFigure 16.14 Goiter, a disease caused by iodine deficiency, results in the inability of the thyroid gland to form T3 and T4 . The body typically attempts to compensate by producing greater amounts of TSH. Which of the following symptoms would you expect goiter to cause? a. Hypothyroidism, resulting in weight gain, cold sensitivity, and reduced mental activity. b. Hyperthyroidism, resulting in weight loss, profuse sweating and increased heart rate. C. Hyperthyroidism, resulting in weight gain, cold sensitivity, and reduced mental activity. d. Hypothyroidism, resulting in weight loss, profuse sweating and increased heart rate.
- Hormones are chemical signaling molecules produced by specialized cells and transmitted via the circulatory system to all other cells in the body. Which of the following describes a condition that needs to be met for a target cell to re- ceive the signaling molecules? A B с D The size and shape of the target cell needs to be similar to that of the cell that secreted the hormone. The location of the target cell needs to be within the local region of the cell that secreted the hormone. The target cell needs to have sufficient ATP to transport the hormone into the cell. The cytosol of the target cell has to have receptors that recognize and bind the hormone.Place 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.Some cancer cells release their own grown hormone rather than relying on growth hor- mones from elsewhere in the host organism. Which of the following describes the type of cell communication used by these cancer cells to promote their continued division? A juxtacrine signaling B с D endocrine signaling paracrine signaling autocrine signaling
- Thyroid cancer results when the cells in the thyroid gland divide uncontrollably. Individuals who have excessive exposure to radiation may have higher chance of getting thyroid cancer. Thyroid cancer can be treated through surgery, iodine therapy, radiotherapy, and/or chemotherapy. What is the purpose of prescribing thyroxine medication for patients following the surgical removal of the thyroid gland? Select one: a. to decrease TRH and increase TSH levels b. to increase TRH and TSH levels c. to decrease TRH and TSH levels d. to increase TRH and decrease TSH levelsA hydrophilic peptide hormone is produced in the anterior pituitary gland located at the base of the brain. The hormone targets specific cells in many parts of the body. Which of the following best explains a possible mechanism that would enable the hormone to efficiently reach all the target cells in the body? A. Restate the question and record the right answer. B. Why is this the correct answer?Insulin-like growth factor (IGF) is a peptide hormone (ligand) that binds and activates IGF receptor tyrosine kinase. Once the ligands bind the receptors, the cell undergoes cell division and multiply. Therefore, IGF is important for the growth of muscle and bone tissues during puberty. The way the IGF hormone works is that the hormone-bound IGF receptor tyrosine kinase increases the levels of cyclins inside of the cell and promotes the progression of the cell cycle. Describe how receptor tyrosine kinase works in a general sense and how cyclins regulate the cell cycle.
- Identify which of the following hormones characteristically regulates the activity of the cell whose nucleus is marked by the arrow in the two images below? (A) luteinizing hormone (B) gonadotropin-releasing hormone (C) 5-alpha-reductase (D) follicle-stimulating hormone (E) inhibinHormones are signaling molecules that can alter cellular activity and gene expression. Hormones also have diverse chemical structures. How does the chemical nature of different classes of hormones influence how/where it interacts with target cells?Cells that have receptors for the hormone, where they eventually end up to cause hormonal action are called
