Correct Answer � A Explanation |
 |
– GM1 ganglioside is the receptor for cholera toxin.
– Cholera, caused by *Vibrio cholerae*, features “rice watery” stools.
– The cholera toxin binds GM1 ganglioside on intestinal cells.
– This binding triggers processes causing excessive water & electrolyte secretion.
