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.
The site where RNA polymerase attaches to the DNA molecule to start the formation of mRNA is called a?
The site where RNA polymerase attaches to the DNA molecule to start the formation of mRNA is called a promoter region. This region contains specific nucleotide sequences that signal the start of transcription.
What is the major molecule in plants?
The major molecule in plants is cellulose. Cellulose is a polysaccharide that forms the structural component of plant cell walls, providing rigidity and support to plant cells and tissues. It is one of the most abundant organic compounds on Earth.
The signal transduction pathway in animal cells that use epinephrine?
Epinephrine binds to its receptor on the cell membrane, activating the G protein coupled receptor. This leads to activation of adenylyl cyclase, which produces cyclic AMP (cAMP). cAMP activates protein kinase A, which phosphorylates target proteins to carry out the cellular response, such as glycogen breakdown in muscle cells.
What is the function of receptor proteins?
Receptor proteins are designed so special molecules can bind to them, and send messages to the cell that trigger some sort of reaction within the cell.They are embedded in either the plasma membrane or cytoplasm of a cell, to which a mobile signaling (or "signal") molecule may attach.Sources: http://en.wikipedia.org/wiki/Receptor_proteins

What amplifies communication from a signal molecule?
Receptor proteins on the cell membrane or inside the cell amplify the signal from a signal molecule by initiating a cascade of intracellular events, leading to a cellular response. This amplification allows the cell to respond effectively to low concentrations of the signal molecule.
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.
A what amplifies the communication from a signal molecule?
A receptor amplifies the communication from a signal molecule by triggering a series of intracellular signaling events upon binding to the molecule. This signal amplification allows for the coordination of complex cellular responses to the original signal molecule.
What happens to proteins that lack er signal sequence?
Proteins that lack an ER signal sequence are released into the cytosol.
What is the major molecule in plants?
The major molecule in plants is cellulose. Cellulose is a polysaccharide that forms the structural component of plant cell walls, providing rigidity and support to plant cells and tissues. It is one of the most abundant organic compounds on Earth.
What is the role of cAMP in the signal transduction pathway activated by epinephrine?
It binds to and activates protein kinase A, which then phosphorylates other enzymes.

What do signal molecules bind to in cells?
Receptor Proteins
What prevents ALL cells form responding to a signal molecule and instead limits the signal to a TARGET cell?
Not all cells respond to a signal molecule because only target cells possess specific receptors that bind to the signaling molecule. These receptors are typically proteins on the cell surface or within the cell, and they are uniquely expressed in certain cell types. Additionally, the presence of downstream signaling pathways in target cells allows them to respond appropriately to the signal, while non-target cells lack the necessary machinery to interpret or transmit the signal. This selective response ensures that only specific cells are activated, allowing for precise communication and regulation within the body.
