Follicle Cells Synthesize a Protein Called

Question

Follicle cells synthesize a protein called
A) calcitonin.
B) thyroglobulin.
C) transthyretin.
D) albumin.
E) colloid.

Accepted Answer

Follicle cells in the thyroid gland synthesize thyroglobulin, which is then converted into thyroid hormones. Calcitonin is produced by C-cells in the thyroid gland, transthyretin (formerly known as prealbumin) is synthesized in the liver, and albumin is produced in the liver as well. Colloid is a gel-like substance found within the thyroid follicles, but it is not synthesized by follicle cells.
