Increased Cytosolic [Ca²⁺] Involved in Signaling Can Originate From

Question

Increased cytosolic [Ca²⁺] involved in signaling can originate from A) Influx from the extracellular fluid through channels on the plasma membrane B) Efflux from the mitochondria into the cytosol C) Efflux from stores in the endoplasmic reticulum through RyR or IP3receptors D) Release from binding sites within the cytosol E) A and C are correct

Accepted Answer

Increased cytosolic calcium involved in signaling can originate from both the influx from the extracellular fluid through channels on the plasma membrane and the efflux from stores in the endoplasmic reticulum through ryanodine receptors (RyR) or inositol trisphosphate receptors (IP3 receptors).
