Which is NOT a part of the events that result in parathyroid hormones control of blood calcium levels?

a) In response to low Ca2+ levels, cells of the parathyroid gland speed up synthesis of PTH (parathyroid hormone)
b) PTH acts on the kidneys to decrease excretion of calcium in the urine
c) PTH stimulates the conversion of vitamin D into its active form (calcitriol)
d) PTH acts on the parafollicular cells of the thyroid gland to increase the level of the hormone calcitonin
e) PTH increases the number and activity of osteoclasts which dissolve bone matrix and release Ca2+ to diffuse into the blood stream
