Microorganisms and Disease The "A" subunit of diphtheria toxin lysis macrophages with the release of cytokines cause ADP ribosylation of a factor involved in protein synthesis binds host cell receptors found on heart cells forms cAMP that leads to fluid accumulation lysis macrophages with the release of cytokines cause ADP ribosylation of a factor involved in protein synthesis binds host cell receptors found on heart cells forms cAMP that leads to fluid accumulation ANSWER DOWNLOAD EXAMIANS APP
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 ADP ribosylation of guanylate cyclase that stimulates production of cGMP ADP ribosylation of adenylate cyclase that stops production of cAMP 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 guanylate cyclase that stimulates production of cGMP ADP ribosylation of adenylate cyclase that stops production of cAMP 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 ANSWER DOWNLOAD EXAMIANS APP
