- Each steroidogenic organ has all the enzymes necessary to produce any steroid hormone. (True or false?)Give two examples of feedback control of hormone activity.List the major categories of hormones on the basis of their chemical structure. Describe how hormones interact with tissues to produce a response. Describe three methods of regulating the release of hormones.
- Identify the three chemical classes of hormones, and give an example of each. Most hormones belong to which class?Which of the statements is/are incorrect for hormones? 1) Hormones are non-nutrient chemicals serving as intercellular messengers. 2) Hormones are molecules of low molecular weight and are produced in traces. 3) Hormones give energy and also effect metabolism and growth activities of target cells. 4) Many hormones are produced in inactive form.Identify the chemical classes of hormones, and give an example of each.
- Complete the following table that shows the hormones responsible and organs responsible in the body that are used in many homeostatic mechanisms. Identify the functions of eachNeuroendocrine glands are glands that are made up of both nervous tissue and endocrine tissue. This means that they can be directly stimulated by the nervous system to produce or release hormones. i) From what you have learned so far in the course, identify two endocrine glands that are considered to be neuroendocrine. Be specific. ii) Describe a situation/example for each, that demonstrates this function.Describe the main chemical groups of hormones (i.e. peptide / protein, amino acid derivatives, steroids, fatty acid derivatives) and that some are fat-soluble, others are water-soluble and that it is related to the chemical structure. Describe which hormones are released from different endocrine glands in different parts of the body, and transported via the blood to the target organ.
- 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.Give 3 examples of a hormone and provide the following information of each hormone: a. where is the hormone produced? b. target organ of the hormone c. function of hormoneOne of the main endocrine glands in the human body is the pituitary gland. This gland produces a variety of hormones with different effects. Among these are a heterogeneous group of hormones called tropic hormones, which directly stimulate the secretion of other hormones from downstream endocrine glands. Which of the following are tropic hormones? Select all that apply. LH Prolactin Oxytocin ACTH TSH testosterone
