What would be an example of a protein receptor initiating a signal transduction cascade?
An example of a protein receptor initiating a signal transduction cascade is the insulin receptor. When insulin binds to its receptor on the cell membrane, it activates the receptor’s intrinsic kinase activity, leading to autophosphorylation. This event triggers a cascade involving the phosphorylation of downstream signaling proteins, such as IRS (Insulin Receptor Substrate), which then activates pathways like the PI3K/Akt pathway that regulate glucose uptake and metabolism. This signaling ultimately leads to physiological responses, including increased glucose transport into the cell.

Which action is an example of a cell membrane receiving and sending messages?
An example of a cell membrane receiving and sending messages is the process of signal transduction involving receptor proteins. When a signaling molecule, such as a hormone, binds to a receptor on the cell membrane, it triggers a conformational change that initiates a cascade of intracellular events. This can lead to the release of secondary messengers, which propagate the signal within the cell, effectively sending a message in response to the external signal.
What is a signal transduction pathway?
A signal transduction pathway is a group of proteins that carry out transducing signals (which means it converts signals from outside the cell to a different signal inside the cell). A good example can be viewed when a hormone binds to the receptor in the plasma membrane (outside the cell), the receptor which has now been activated can now interact with intercellular proteins which produce new signals inside the cell.
What is a channel linked receptor?
A channel linked receptor transduces functions of the same protein molecule. An example of a channel linked receptor are neurotransmitters in the brain.
What are sensory transduction?
The transduction is a process which passes messages from cell surface to inner components of the cell. For example: uptake or release of glucose, protein synthesis, etc.
The same receptor can have different effects depending on the properties of the?
ligand that binds to it. For example, a receptor can trigger different signaling pathways or cellular responses if it binds to different ligands, even if they bind to the same binding site on the receptor. This is known as ligand-dependent receptor activation.

How does a transmembrane receptor cause the stimulation of a cell does it take something from the chemokine and feed it through its transversile midsection and into the cell giving it to a transport?
N. Take a G protein linked receptor for an example. The ligand docks and causes a conformational change that causes a G protein to dock with the transmember protein receptor and initiate signal transduction through secondary messengers.

Who got noble prize for discovering G protein?
G proteins were discovered when Alfred G. Gilman and Martin Rodbell investigated stimulation of cells by adrenaline. They found that, when adrenaline binds to a receptor, the receptor does not stimulate enzymes directly. Instead, the receptor stimulates a G protein, which stimulates an enzyme. An example is adenylate cyclase, which produces the second messenger cyclic AMP. For this discovery, they won the 1994 Nobel Prize in Physiology or Medicine.

Which of the following drugs is an example of a selective 5-HT receptor agonist?
midril
Proteins each of which has a three dimensional shape complementary to that of a specific signal molecule?
You are likely referring to receptor proteins. Receptor proteins are used extensively in the endocrine, nervous and immune systems to carry out signal transduction and communication between cells. For example, an endocrine receptor may be the insulin receptor, which dimerizes upon signal molecule (insulin) binding and induces a series of changes in the cell leading to increased glucose uptake, increased glycolysis and decreased gluconeogenesis. A nervous system receptor may be a neurotransmitter receptor located at synapses that induces an action potential in the downstream neuron if it binds to a neurotransmitter released by the upstream neuron. The immune system makes extensive use of receptors and these receptors may be cell-surface bound or even soluble (e.g. antibodies). They are involved either in recognizing foreign molecules, transmission of activation signals for leukocytes, or administration of death (apoptosis) signals to other kinds of cells.
What is specialized transduction?
Specialized transduction is a type of bacterial gene transfer where specific genes are transferred from one bacterial cell to another via a temperate bacteriophage. Unlike generalized transduction, which can transfer any bacterial gene, specialized transduction only transfers specific genes located near the prophage integration site in the bacterial chromosome.
When one cell releases a chemical message and it travels and binds to the receptor of another cell is an example of what?
it is called inflation
