Neuronal cells on your taste buds initiate an action potential when they detect specific flavor molecules. Cell surface proteins that detect flavor molecules and initiate an action potential could be:
Select one:
a. potassium leak channels
b. intracellularly ligand-gated sodium channels
c. aquaporin channels
d. mechanically gated channels
e. extracellularly ligand-gated sodium channels
Homework Answers
Answer is e. extracellular ligand-gated sodium channels
because when any flavor come in contact to the taste buds, the extracellular sodium ion starts entering inside the cells and initiate the action potential.

If necessary, refer to Animation: Chemical Synapses. When an action potential reaches the axon terminal: sodium ions are released from the axon terminal, enter the cell body of the postsynaptic neuron through its sodium channels, and may initiate an action potential in that neuron. neurotransmitter molecules are released from the axon terminal and bind to receptors on the postsynaptic neuron, causing either an inhibitory hyperpolarization or an excitatory depolarization. neurotransmitter molecules are released from the axon terminal, bind to and...

Neurons are electrically excitable cells in the nervous system that function to process and transmit information from one part the body to another, through specialized connections called synapses. The signaling process is partly electrical and partly chemical. In vertebrate animals, neurons are the core components of the brain, spinal cord and peripheral nerves. Neurons carry messages in the form of electrical signals called nerve impulses or action potentials. An action potential occurs when the resting membrane potential at a specific...
