Received information is called a transduced signal because: this process often has many steps of information conversion. it is then converted into other electrical forms. it is then converted into other chemical forms. many different molecules form a signaling cascade. it is then converted into other chemicals during metabolism.

How is the response to a signal regulated? Why is it often specific? Expain step by step in simple words please.
When a signaling molecule binds to a receptor located in the cell membrane, the signal / information is carried further into the cell via the receptor. The signal / information will lead to some type of change inside in cells in response to the signal it received. What this change is depends on the type of signaling molecule that binds to the cell (but may also depend on the type of cell that the signaling molecule binds to). In some cases, the change that takes place in the cell will be rapid and take a few seconds off that the signaling molecule binds to the receptor until the change takes place (fast signaling pathway). In some cases the change will take much longer, perhaps several hours from the time the signaling molecule binds to the receptor until the change occurs in the cell (slow signaling pathway). Explain how the signal path would be be able to look when it is fast and what it could look like when it is slow.
When signals bind to the protein receptors, it depends if the receptor is found on the nuclear or cell membrane. genes are turned on or off. gates open up and then there is a cellular response, such as an action potential. the receptor changes its shape in order to bind the signal and to function.
In _____________ signaling the signal molecule is active within the cell that produces it.
During signal transduction (a) the cell converts an extracellular signal into an intracellular signal that leads to a change in some cell process (b) a signaling molecule directly activates or represses several genes (c) each enzymecatalyzes production of one molecule of product (d) enzymes in the signal cascade remain active until the last component of the pathway alters a cellular process (e) the signal is terminated by cyclic AMP
Compound C is a pharmaceutical agent that blocks AMPK activity. How might compound C influence adaptation following resistance exercise? How might compound C influence adaptation following endurance exercise? Be specific and remember this section is Molecular Signaling
Select the correct order of signal transduction / cell communication / cell signaling. Reception - Response - Amplification Amplification - Reception - Response Response - Reception - Amplification Reception - Amplification - Response
A drug binds to a receptor and causes an immediate change in the electrical signaling or excitability of that cell, without activating another signaling molecule. What type of receptor is this drug most likely binding to? G-protein coupled receptor (GPCR) Ligand-gated ion channel Enzyme-coupled receptor Intracellular receptor Voltage-gated ion channel
__________ are molecules released from a signaling cell that have effects on target cells. a. Hormones b. Neurotransmitters c. Local signaling molecules d. Pheromones e. a and b f. all of the above
The propagation and reception of signals between nerve cells must happen quickly, in order for an organism to respond to stimuli appropriately. Because of that, the majority of neurotransmitters fall into which category? -Autocrine -Paracrine -Endocrine -Direct signaling
DO NOT COPY IN GOOGLE OR IN BARTLEBY QUESTION: Drugs and other medecine uses the concept of signaling. Cite some drugs how they mimic natural signal molecules.
A cell within organ A expresses a protein that is secreted from the cell and travels through the organism’s blood stream to a cell on a distant organ B. The protein binds to a receptor protein on the cell surface of organ B and activates an intracellular signaling pathway resulting in altered gene expression patterns in the cells. What form of intercellular signaling does this represent? Contact-dependent? Paracrine? Synaptic? Endocrine? Autocrine?
