Select all of the following that are correct regarding how hormones reach their target cells' receptors. Question 1 options: amino acid derived proteins must bind extracellularly to effect changes intracellularly water-soluble hormones are a first messenger and initiate a signaling cascade carried out intracellularly by a second messenger steroid hormones and their receptors bind directly to DNA to affect transcription steroid hormones are lipid-soluble and can slip through the lipid bilayer of cells to reach receptors in the cytosol or nucleus

Step 1
" - This statement is correct. Amino acid-derived hormones (like peptide hormones) are typically water-soluble and bind to receptors on the cell surface, which then triggers intracellular signaling pathways. Show more…

1. hydrophilic hormones a. are excreted by exocytosis into the blood stream b. are taken up by the target cell via endocytosis c. diffuse into the target cells plasma membrane d. bind to receptors in the cytoplasm 2. Steroid hormones bind to receptors in the cytosol of the target cells and then this complex moves into the nucleus to stimulate transcription. a. true b. false 3. which statement(s) regarding hydrophilic hormones is correct? a. they bind to the receptors on the cell membrane of the host cells b. they trigger the release of messenger molecules inside the target cells c. epinephrine is an example of a water- soluble protein d. all the choices are correct

11) Study the following steps showing how a steroid hormone changes the activities of its target cells: Determine the order in which the steps take place. Write the number of each step in the space provided: The hormone attaches to the receptor in the cytoplasm, forming a hormone-receptor complex. Proteins that alter the cell's activities, such as enzymes, are made. The steroid hormone passes through the cell membrane. A gene in the DNA is activated, and transcription and translation take place. The hormone-receptor complex enters the nucleus of the cell and binds to the DNA. 12) Study the following steps showing how an amino acid-based hormone changes the activities of its target cells: Determine the order in which the steps take place. Write the number of each step in the space provided.
Which statement is true? Steroid hormones bind to a receptor in the plasma membrane while water-soluble hormones pass directly through the target cell's membrane. The concentration of hormones in the blood remains constant to maintain homeostasis. When a hormone binds to a specific receptor in the target cell, it triggers a series of reactions inside the cell. Compared to the actions of the nervous system, the hormones of the endocrine system have faster and longer-acting effects on a broader range of cell types. Exocrine glands secrete chemical messengers called hormones directly into the bloodstream, which transports the hormones throughout the body.
