Which of the following inorganic molecules is used by cells as a second messenger?
A) calcium ions
B) carbon monoxide
C) nitric oxide
D) potassium ions

Question

Quizplus · Accepted Answer

Calcium ions are commonly used as second messengers in cellular signaling pathways. They play a crucial role in many signaling cascades, including those involved in muscle contraction, neurotransmitter release, and gene expression. Carbon monoxide and nitric oxide are both involved in cellular signaling, but they typically function as gasotransmitters rather than second messengers. Potassium ions also play important roles in cellular signaling, but they are not commonly used as second messengers.
