Receptors that form ion channels

Receptors that link to tyrosine kinase

Receptors that bind to DNA

Membrane bound receptors

 Receptor linked to G proteins

That the post-synaptic cell RMP would be unchanged

That the post-synaptic cell RMP would become less hyper-polarized

That the post-synaptic cell RMP would become more hyper-polarized

That the post-synaptic cell RMP would become more less de-polarized

That the post-synaptic cell RMP would become more de-polarized

Controls how well the natural ligand binds to the receptor

Determines the specificity of the receptor

Coordinates cellular effects following receptor activation

Does not affect receptor-ligand interactions

Is the major binding site of a receptor

Only if the cell needs to have high affinity responses

To produce an intracellular response

Only if an ion channel needs to be opened or closed

Only if an intracellular G protein needs to be activated

Only if the cell needs to have high specificity responses

the post-synaptic cell RMP would become hyper-polarized

the post-synaptic cell would activate G proteins

the post-synaptic cell would activate G proteins to activate enzymes

the post-synaptic cell RMP would become de-polarized

the post-synaptic cell RMP would become polarized

Because receptor shape depends on the amino acid sequence of the polypeptide chain

Because receptor affinity is not absolute for the shape of the entire ligand

Because receptor shape depends on the amino acid sequences of the proteins involved

Because receptor specificity is not absolute for the shape of the entire ligand

Because ligand shape depends on the amino acid sequences of the proteins involved

growth factors

steroid hormones

vitamin B

neurotransmitters

cytokines

Makes the receptor selective for ions

Is the factor that allows the receptor to saturate quickly

Is due to the shape of the binding site on the receptor

Arises because the receptor is made of amino acids

Allows the water-filled pore to open or close

a steady state exists, maintained by the activity of the sodium-potassium pump

the cell membrane is impermeable to chloride ions

the cell membrane is more permeable to sodium than to potassium ions

the electrochemical gradient for potassium ions is inwardly directed across the cell membrane

the transmembrane potential difference is equal to the potassium equilibrium potential
