Ionized calcium is an important second messenger in a great variety of cellular responses to stimuli, both chemical and electrical. Review one signaling pathway in which Ca^(2+) acts as a second messenger by correctly completing each sentence below.
To begin, cytosolic Ca^(2+) can be increased by the opening of receptor activation from a first messenger. in the plasma membrane or by
With receptor activation, the receptor itself may contain a Ca^(2+) channel, or the receptor may activate a that opens the channel via a second messenger.
It is also possible that Ca^(2+) is released from the this is mediated by Click to select) vv or Ca^(2+) entering from the extracellular fluid.
When cytosolic Ca^(2+) concentrations are elevated, Ca^(2+) can act as a second messenger. One of the main protein targets of Ca^(2+) is (Click to select) ✓. The resulting Ca^(2+)-calmodulin complex can activate or inhibit a large variety of enzymes and other proteins, leading to the cellular response.
