Final answer:
A tetrodotoxin molecule contains carbon, hydrogen, nitrogen, and oxygen. These elements form the potent neurotoxin's molecular structure.
Step-by-step explanation:
A molecule of tetrodotoxin contains several different elements. These elements comprise carbon (C), hydrogen (H), nitrogen (N), and oxygen (O).
Tetrodotoxin is a potent neurotoxin. For instance, the formula for a simple compound composed of sulfur and fluorine is sulfur hexafluoride (SF6). Similarly, compounds like dinitrogen trioxide (N2O3) clearly show the quantities of their constituent elements in their chemical formulas.
