As mentioned in the case description, tetrodotoxin is a molecule that blocks voltage-gated sodium ion channels. Describe the structure of a sodium ion. a. A sodium ion (Na+) occurs when a sodium atom loses an electron and gains a positive charge 3. What is a voltage-gated sodium ion channel? What is it made of? What is its function? a. A voltage-gated sodium ion channel opens when there is a change in the voltage of the membrane and allows sodium ions to flow across its electrochemical gradient. These voltage-gated channels are made up of amino acids and they aid in generating and moving an action potential down a membrane or axon (Brooker, Robert, 106). 4. Why do sodium ions need channels to move in and out of cells? a. Most cell membranes are selectively permeable, meaning
