White blood cells migrate to a source of infection by amoeboid migration along the surfaces of endothelial cells. Imagine you have discovered a toxin that suppresses the immune system by specifically inhibiting pseudopod formation in white blood cells. Which of the following is your toxin's most likely mechanism of action? O It interferes with the interaction between actin monomers. O It prevents hydrolysis of GTP. O It causes Ca+ + to leak out of the smooth ER. O It prevents ATP hydrolysis.

Maddox · Answer 1

t interferes with the interaction between actin monomers

Explanation:

When the toxin attacks, it affects the formation of pseudopods that are directly related to the presence of actin responsible for movements in the white blood from the assembly and disassembly processes in the cytoplasm of these cells.
