Explain what will happen in an axon undergoing an
action potential but which
is unable to utilize monosaccharides
for cellular respiration.
If a neurone is unable to utilize monosaccharide for cellular respiration it will effect ATP production. ATP reserve will be depleted a no more new ATP can be synthesized. ATP is not directly required for action potential.but ATP essential for the maintenance of resting membrane potential by sodium potassium pump, which utilizes ATP.
Once the ATP reserve of neurone is completely depleted resting membrane potential cannot be maintained because sodium potassium pump requires ATP. It will affect the action potential.

What is the relationship between the arrival of an action potential (nerve impulse) at the axon terminal and exocytosis of neurotransmitters?
What is the difference between ion and flow and cellular response when an action potential is heading down an axon and when an action potential is about to reach synaptic potential?
The resting membrane potential of a neuronal axon is -70 mV. When an action potential is triggered, Na+ ions move into the axon, which reverses the voltage, bringing it towards 0 mV. Which of the following is the correct term for this sequence of events? a. Repolarization b. Hyperpolarization c. Depolarization d. Hypopolarization e. Isopolarization
What factors determine how fast an action potential will travel along an axon?
neuronal action potential reaches the axon terminal of neuron _______ are released from the axon terminal by ______ _______ diffuse across the _______ _______ and bind to ______ on the postsynaptic membrane of neuron, 2) generating an excitatory local potential, if the neuron is stimulated enough time, the excitatory local potentials _______ and spread through the neuron's plasma membrane toward the axon, when the trigger zone is deploarized to ______, an ______ is generated
Question 17 (6 points) Consider the typical action potential. Predict what would happen and how the appearance of the action potential graph would change if voltage-gated potassium channels are unable to open.
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...
The action potential travels down: A. the dendrite. B. the synapse. C. the axon. D. both the dendrite and axon.
Describe the events of an action potential is conducted down the membrane of an axon and how it is transmitted to another cell across a synapse causing an IPSP or an EPSP.
Describe briefly how myelination of the axon speeds up the conduction of the action potential. What is the molecular process that is altered? Maximum number of characters (including HTML tags added by text editor): 32,000 Show RichText Editor and character count) 1
