What is the job a a receptor molecule?
A receptor molecule is a molecule that receives information from outside the cell. They are embedded in either the plasma membrane or cytoplasm of a cell. A specific molecule on the surface or inside of a cell with a characteristic chemical and physical structure. Many neurotransmitters and hormones exert their effects by binding to receptors on cells.
Which molecule has a binding site for calcium?
Calmodulin is a calcium-binding protein that has a binding site for calcium ions. It is involved in the regulation of various cellular processes by binding calcium and transducing the signal to downstream effectors.
What binds to a signal molecule enabling the cell to respond to the signal molecule?
A receptor protein on the cell membrane binds to the signal molecule, initiating a series of intracellular events that lead to a cellular response. The binding of the signal molecule to the receptor triggers a signaling cascade that ultimately activates specific cellular pathways.
How do receptor membrane proteins facilitate cellular communication and signal transduction processes within the body?
Receptor membrane proteins play a crucial role in cellular communication by binding to specific signaling molecules, such as hormones or neurotransmitters. This binding triggers a series of events inside the cell, known as signal transduction, which ultimately leads to a cellular response. By recognizing and responding to external signals, receptor membrane proteins help coordinate various processes within the body, such as growth, metabolism, and immune response.
Explain how an original signal molecule can produce a cellular response when it may not even enter the target cell?
There are a few ways that this happens. One way is through synaptic signalling. This signalling occurs in the nervous system. An electric signal along a nerve cell triggers the secretion of a chemical signal in the form of neurotransmitter molecules. These diffuse across the synapse, these neurotransmitters stimulate the target cell. Another type of signalling is paracrine signalling. The secreting cell acts on nearby target cells by discharging molecules of a local regulator like a growth factor into the extracellular fluid. Both animals and plants use hormones for long distance signalling. With this cell communication, specialized endocrine cells secrete hormones into body fluids, often the blood. Hormomes may reach virtually all body cells. What happens when a cell encounters a signal? The signal must be recognized by a specific receptor molecule, and the information it carries must be changed into another form, transduced before the cell can respond. So generally the cells generally communicate via chemical messengers targeted for cells. Addition of general pathways:A signal molecule such as a peptide hormone produce a cellular response by binding to receptor proteins on the cell membrane. These molecules may be involved in endocrine (systemic-global), paracrine (tissue-local), autocrine (self-local), or nervous (restricted to synaptic junctions) signaling. The receptor proteins for these signal molecules have very high specificity for a particular kind of molecules and respond by either directly opening a gated channel, creating a secondary messenger molecule, or directly phosphorylating downstream molecules to initiate a signal cascade that result in a subtle or gross alteration in the cell's state of operation through the activation/deactivation of enzymes and the activation/deactivation of transcription factors controlling gene expression. Recurring archetypes of these receptors include ligand gated channels (example: acetylcholine receptors in neuromuscular junctions. Binding of acetylcholine causes the opening of ion channels that propagate the action potential), G-protein coupled receptors (example: adrenergic receptors. Binding of adrenaline initiates G-protein activation and results in the production of secondary messenger molecules cAMP, which activate downstream target molecules that effect changes), Receptor tyrosine kinases (example: insulin receptor. Binding of insulin leads to the recruitment of downstream proteins and their activation through phosphorylation on tyrosine residues).
What Bonds to a molecule and sends signal to the inside of cell?
Receptors on the cell membrane bind to specific molecules, known as ligands, which can include hormones, neurotransmitters, or other signaling molecules. This binding triggers a conformational change in the receptor, initiating a signal transduction pathway that transmits information to the inside of the cell. This process often involves the activation of secondary messengers or other intracellular signaling proteins, leading to a specific cellular response.

How the modem change the analog signal?
MODEM stands for modulator/demodulator. Outgoing it modulates a carrier wave with information and transmits this data on a wire or through the air. When it receives a modulated signal it demodulates the signal and separates out the information.
Is saying that a device transmits a signal correct?
Yes, it is correct
What drug that interferes with the binding of signal molecules to receptor proteins in the heart muscles?
Beta-blockers are drugs that work by interfering with the binding of signal molecules (such as adrenaline) to beta-adrenergic receptors in the heart muscles. By doing so, beta-blockers reduce the heart rate and blood pressure, making them useful in treating conditions like hypertension and heart failure.

What are neurontransmitters?
a chemical that transmits a nervous systems signal across a synapse.
Which frequency signal does the mobile phone transmits continuously?
None, as it doesn't transmit continuously.
What molecules store information needed to manufacture protein?
The chromosome. It is very long single thread of DNA. There are many genes, which signal production of the protein molecules.
What are radioactive probes?
Radioactive probes are molecules that are labeled with a radioactive isotope, such as ^32P or ^35S, which emit radiation that can be detected. They are commonly used in molecular biology to detect specific DNA, RNA, or protein molecules by binding to complementary sequences and producing a signal that can be visualized.
Signal molecules bind to?
specific receptor proteins on the surface of target cells, triggering a cellular response. This binding initiates a signaling cascade that ultimately leads to changes in the cell's behavior or function. The specificity of the interaction between the signal molecule and its receptor ensures that only the appropriate cells respond to the signal.
