Describe the catecholamines. Give one example. Describe steroid hormones. Give one example. How are they different in their action and why?

Below are structures of several steroid hormones derived from cholesterol. Circle the steroid nucleusin each.

Explain how second messenger molecules work. Why use a second messenger rather than simply relying on a more direct hormone-stimulated transduction mechanism?

Why is this wrong?

After reading about hormones, please write a paragraph:  What could happen to hormone function if target cells receptors are structurally incorrect?

Steroid hormones find their receptors inside of cells. True or Flase? This is true. Explain why this is not false

Explain how a second messenger works. Why use a secondmessenger rather than simply relying on the original hormone to produce the desired effect?

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 hormone

determine the principle involved or color reaction mechanism of each steroid. progesterone with sulphuric acid   methyl testosterone with sulphuric acid   prednisone with sulphuric acid   androsterone with sulphuric acid

Create a hormone map. A complete map will include the secretion signal for the hormone, the origin of the hormone, and hormone targets, and the physiological outcomes of hormone increases or decreases within the body. Be sure to indicate feedback loops within your map. Please provide an explanation of the steps within your map and explain why this interaction is important physiologically.
