The central lumens of thyroid follicles are filled with colloid, which consists of the protein thyroglobulin, a molecule that binds and stores thyroid hormone.
Thyroglobulin is a protein produced primarily by the thryroid gland. The thyroid gland is mainly made up of tiny, round shaped structures called follicles that produce and store thyroglobulin. Thyroglobulin acts as a substrate for the synthesis of the hormones (thyroxine and triiodothyronine) and also the storage of the inactive forms of thyroid hormone and iodine. Thyroxine and triiodothyronine assist in the regulation of the utilization of energy by the body.

Answer:
41 minutes
Explanation:
According to this question;
- Roberto spent 90 minutes doing homework
- Roberto spent 2/3 hour reading. Since 1 hour = 60 minutes
2/3 hour = 2/3 × 60 = 40 minutes.
- Roberto spent 540 seconds making his lunch for the next day. Since, 60 seconds = 1 minute
540 seconds = 540/60
= 9 minutes.
The total amount of time Roberto spent reading and making his lunch is = 40 + 9 = 49 minutes.
Therefore, the amount of time Roberto spent doing his homework than reading and making his lunch is (90 - 49) = 41 minutes.
