Common elements that occur in many signal transduction pathways include which of the following?
A) Specialized domains mediate specific interactions in the pathway.
B) Second messengers may participate.
C) Cell division is usually the result.
D) A and B
E) All of the answers are correct.

Question

Quizplus · Accepted Answer

A and B are correct because specialized domains in proteins often mediate specific interactions within signal transduction pathways, and second messengers like cAMP, calcium ions, and others play crucial roles in these pathways. Cell division is not a universal result of signal transduction pathways, making C incorrect.
