To be considered a target cell for a particular hormone, a cell must …. a) be experiencing a disruption in homeostasis. b) be the same cell type as the one that produced the hormone. c) be capable of producing that hormone. d) be located relatively close to the cells that produced the hormone. e) have receptors that recognize and bind to the hormone.
- Why are the eicosanoids often called “local hormones”?Please identify the incorrect statement about hormone signaling: A) Cystolic receptors bind to hydophobic hormones and transport them into the nucleus where they directly influence protein synthesis. B) Hydropholic hormones cannot pass through the plasma membrane without help. Therefore, there are transport proteins that carry the hydrophillic hormones to the cytosol where it can bind its receptor C) Hydrophilic hormone signalling involves membrane receptors that have the ability to activate adenylyl cyclase, producing cAMP. cAMP then affects the activity of numerous proteins in the cytoplam. D) Hydrophobic hormones easily enter the plasma membrane. Therefore, there is no need for hydrophinic hormone receptors to be on the extracellular surface.Virtually all of the protein or amino acid-based hormones exert their effects through an intracellular O a) ions O b) deactivators c) receptors O d) second messengers Ston sharing Hide
