Activated phospholipase C produces diacylglycerol, which triggers the release of this element inside of the cell, and abscisic acid triggers the influx of this element's ion from vacuoles, causing stomata to close. Parathyroid hormone causes the increased resorption of this element's ion in the distal tubules of the kidney, and this element's ion binds to proteins to initiate SNARE-mediated vesicle fusion in neuronal synapses. Osteoclasts break down a tissue that stores this element, a phosphate

Parathyroid hormone causes the increased resorption of this element's ion in the distal tubules of the kidney, and this element's ion binds to proteins to initiate SNARE-mediated vesicle fusion in neuronal synapses. Osteoclasts break down a tissue that stores this element, a phosphate of which is termed hydroxylapatite. For 10 points, name this alkaline earth metal, an element with a plus-2 oxidation state that is often found in milk and bones.
