Thyroid hormones are important for peroxide produced by mitochondria to iodinate tyro- normal development of the CNS and for body growth. Thyroid peroxidase is localized to the apical hormones, as well as the growth of the thyroid gland. The release of thyroid hormone spond to TSH, thyroid hormone production would be is mediated by lysosomal degradation of thyroglobu- decreased, resulting in poor development of the CNS lin.

In red cells, 2,3-DPG (P50 ↑) levels are much higher than in other cells because erythro- cytes lack mitochondria.
