A certain peptide hormone is produced in the anterior pituitary gland located at the base of the mammalian brain. The hormone targets specific cells in many parts of the body. Which of the following best explains a possible mechanism that would allow the hormone to reach all of the target cells in the body? A B с D The hormone diffuses into target cells adjacent to the anterior pituitary gland and dif- fuses through their cell membrane. The hormone moves through plasmodesmata between cells until it has reached all cells with the correct intracellular binding sites. The hormone interacts with neurons at the base of the brain and directs signals to the target cells through the neuronal network. The hormone is released into the bloodstream, where it is transported to all cells with the correct receptors.

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.
When comparing two or more ligands, a larger numerical value for KD corresponds to a higher binding affinity. True False In radioligand binding assays, a large excess of a noncompetitive antagonist is used to determine the specific binding of the radiolabeled ligand. True False Exocrine glands have ducts that provide a passageway for secretions to move to the surface of the epithelium. True False An inverse agonist binds to a receptor with an affinity that is inversely proportional to its potency. True False Can I get the answer? I don't need explanation

Insulin is a hormone that regulates the concentration of glucose in the circulatory system by activating signal transduction pathways that increase the intake of blood into cells. Individuals with type 1 diabetes are unable to produce insulin, and are therefore unable to effectively regulate their blood-glucose concentration. Which of the following best explains how a medication that triggers the addition of insulin receptors on cells will affect the intake of the insulin signaling pathway in individuals with type 1 diabetes? A B с D The medication will effectively activate the signaling pathway because insulin levels will return to normal. The medication will effectively activate the signaling pathway because the addition of in- sulin receptors will increase insulin synthesis. The medication will have no effect on the signaling pathway because the receptors will not be activated in the absence of insulin. The medication will have little or no effect on the signaling pathway because…

The figure below shows a signaling pathway activated by the bindiıng of adrehalMNe LU the beta-adrenergic receptor. Binding of adrenaline to the receptor causes GTP-binding and activation of G proteins. Active GTP-bound G protein activates adenylate cyclase to initiate a signaling cascade that affects cellular responses, and includes cellular changes to mediate increased heart rate and accounts for the flight-or-fight response. activated adenylate cyclase adrenaline activated B-adrenergic receptor adenylate cyclase G protein subunit 22 GTP SDP conformational ATP CAMP change in receptor heterotrimeric G protein ACAMP inactive protein kinase A active protein kinase A 4 cellular responses Consider the homozygous mutation in which a cell produces a variant of adenylate cyclase that can no longer be activated Which of the following are true in this cell?
