How are G linked protein receptors made?
G-Linked protein receptors are proteins whose N-Terminus faces the cytosol. They are threaded to a translocon and begin with a Signal anchor sequence and alternate 7 times between a signal anchor sequence and a stop transfer anchor sequence before finally finishing synthesis in the cytosol.
Signal molecules bind to?
receptors proteins
Hydrophobic signal molecules can interact with what intracellular receptors?
All receptors - both intra- and extra- cellular - are extremely specific in their interactions.
What are three steps in cell communication?
Successful cell signaling involves a sender, a signal and a receptor or receiver. There are many different ways in which cell signaling can occur, firstly; there are many different types of signals. These can be classified into two main groups, protein/ polypeptide signals and steroid based or hydrophobic signals. Protein/polypeptide signals can only bind to receptors on the plasma membrane of a cell where as steroid based or hydrophobic are able to pass through (because of their hydrophobic nature) the plasma membrane and attach to receptors within the cytoplasm or nucleus. There are many different receptors and ways that cells then continue on cell signaling but that is the basics of it. Once a signal is bound with its receptor a response occurs. It goes: sender >> signal >> reception >> transduction >> response Receptors also include ion-channel linked, and G-protien linked receptors. For the enzyme-linked(most common is receptor thyrosine kinase) the signal transduction goes through RAS, MAP kinase to different specific tartget molecules. Also, short gene expression pathways are mediated through STAT and SMAD. Smile over wrong spellings. Absolute Kevin UNCW
What are the three responses cells generally have to a specific signal?
Cells communicate with other parts of the body by releasing receptors that put particular.

Where is auditory receptors located?
Auditory receptors are located in internal ears. The vestibulocochlear nerve carries the signal from internal ear to brain.
What water-soluble hormone would most likely bind to what membrane proteins?
Channel linked receptors bind to neurotransmitters. (also called ion channels and ligand gated ion channels) A ligand is the signal molecule i.e the neurotransmitter. Hormones bind to intracellular receptors because hormones are non polar and can cross the cell's plasma membrane. (also called cytoplasmic receptors)
How accept the signal in cell?
Cells receive signals through receptors located on the cell membrane
Why do lipid soluble signaling molecules like testosterone cross membranes of all cells but effect only target cells?
Because response of a cell to a signaling requires that the responding cell have receptors that recognize that hormone. Only target cells of a signal have the receptors for the signal.
What is meant by signal related to signals and systems?
signal is a physical quantity.the system which capable of analyzing the signal is the system.
What is the definition of convulation signal and systems?
Convulations
Some enzymatic receptors and most G-protein-coupled receptors carry the signal molecule's message into the target cell by utilizing other substances within the cytoplasm commonly called?
Second Messengers :)
