A&P 2 University Of Memphis -Biol 226 (A&P II) Exam #2 questions with answers Endocrine system - correct answer This system has the following general characteristics: (1) contains ductless glands that produce and secrete chemical messengers called hormones, and (2) the hormones produced travel via the blood stream to specific target cells in order to regulate metabolic processes Fat soluble and non-fat soluble - correct answer What are the two main categories of hormones? This is determined by their anatomy. An increase of hormone levels causes downregulation - correct answer An (Increase / Decrease) of hormone levels causes downregulation. This decreases the amount of receptors so the excess hormones do not have as many binding sites A decrease of hormone levels causes upregulation - correct answer An (Increase / Decrease) of hormone levels causes upregulation. This increases the amount of receptors so as many hormones as possible can bind Inside of the cell within the cytoplasm or nucleus - correct answer For steroids and amine derivatives of tyrosine from the thyroid gland, where are the receptors located? (a hormone-receptor complex is formed) New protein synthesis and the production of more copies of the specific protein. Hormones change the function of the target cell by producing proteins for different tasks - correct answer What do fat soluble hormones stimulate? Genes - correct answer These are the instructions for how to make a protein. A specific one of these on DNA is triggered by a hormone to produce a specific protein The message is slightly amplified as multiple mRNA are created for one specific protein - more than one copy of the single protein is made - correct answer Describe the amplification caused by steroids and amine derivatives of tyrosine from the thyroid gland
