What is a molecule that acts as signal when it binds to a receptor?
Intracellular receptor
What binds to a signal molecule enabling the cell to respond to the signal molecule?
receptor proteins bind to signal molecules
When a signal molecule binds to a receptor protein the receptor protein may change the?
shape.
Why is it important that each receptor protein binds to only one signal molecule?
because every receptor has specific shape on it, which binds with specific molecule.
When a signal molecule such as a growth hormone binds to a receptor protein in the plasma membrane it stays on the outside of the cell. How might the inside of the cell know that the signal has bound?
Due to a conformational change of the receptor protein....
When a hormone molecule binds to a specific protein on the plasma membrane the protein it binds to is called?
... a receptor protein.
What is a molecule such as a neurotransmitter or a hormone that binds to a receptor called?
what are the characteristics of action potentials
When a neuron responds to a particular neurotransmitter by opening gated ion channels the neurotransmitter is serving as which part of the signal pathway?
Signal Molecule Synaptic transmission is when it moves across the synaptic gap, and it then just binds to the receptor on the other side.
An allosteric receptor embedded in a cell membrane will change shape only?
when a signal molecule fits the shape of the receptor
What a receptor protein in a membrane that recognizes a chemical signal is most similar to?
the active site of an allosteric enzymein the cyyoplasm that binds to a pecific substrate
Epinephrine acts as a signal molecule that attaches to proteins?
G-protein-linked receptor
Are gated channels are always open?
Yes, it can a gated ion channel is opened when a signal molecule binds to a receptor protein causing the receptor protein to open the ion channel through the cell membrane and after this process the ion channel is closed once again to prevent various molecules to enter the cell.
