Increases in cytosolic [Ca²⁺] can be involved in the signaling of all of the following EXCEPT A) Stimulus-secretion coupling B) Excitation-contraction coupling C) Excitation-synthesis coupling D) Calmodulin-dependent signaling E) Direct activation of enzymes

Question

Quizplus · Accepted Answer

Increases in cytosolic calcium concentration are known to play a crucial role in various cellular signaling pathways, including stimulus-secretion coupling, excitation-contraction coupling, calmodulin-dependent signaling, and direct activation of enzymes. However, "excitation-synthesis coupling" is not a recognized process directly involving cytosolic calcium increases in the same manner as the others.
