Mutation of the calmodulin gene would alter the ability of ____________ to act as a second messenger.
A)calcium
B)sodium
C)potassium
D)cAMP

Question

Quizplus · Accepted Answer

Calmodulin is a protein that binds to calcium ions, allowing them to act as a second messenger in a variety of cellular signaling pathways. Mutation of the calmodulin gene could potentially alter the ability of calcium to act as a second messenger. Sodium and potassium are not directly involved in second messenger signaling, and cAMP is a second messenger that operates independently of calmodulin.
