Microorganisms and Disease Cholera toxin is an A-B type toxin in which the B portions bind to a receptor on a host cell and the A portion enters the cell to cause cleavage of rRNA that results in disruption of ribosome function ADP ribosylation of a G protein that locks it into an active form that stimulates adenylate cyclase to make cAMP ADP ribosylation of adenylate cyclase that stops production of cAMP ADP ribosylation of guanylate cyclase that stimulates production of cGMP cleavage of rRNA that results in disruption of ribosome function ADP ribosylation of a G protein that locks it into an active form that stimulates adenylate cyclase to make cAMP ADP ribosylation of adenylate cyclase that stops production of cAMP ADP ribosylation of guanylate cyclase that stimulates production of cGMP ANSWER DOWNLOAD EXAMIANS APP
