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.
When an organism uses fatty acids, the ester linkages of triacylglycerols are hydrolyzed by enzymes called lipases.
Lipases hydrolyze triglycerides into their constituent fatty acid and glycerol molecules. Lipase digestion starts in the lumen of the small intestine. The surface tension of the fat droplets is decreased by bile salts so that the lipases can hydrolyze the triglyceride molecules.

Before starting a cleaning task, what should be done is to sanitize first to make sure the cleaning product will work effectively (option A)
<h3>What are the stages of cleaning?</h3>
The stages of cleaning includes the following
1. Pre- Cleaning
The first stage of cleaning is to remove loose debris and substances from the contaminated surface you’re cleaning. You can do this by wiping with a disposable towel, sweeping, or rinsing. This process is also called sanitation. The aim is to remove as much substance as possible to prepare the area for the next stage of cleaning.
2. Main Cleaning
The second stage of cleaning is to loosen any substances, dirt, grease, and debris that you were unable to remove during the pre-clean stage. This involves using hot water and a detergent.
3. The Thirdstage of cleaning is to disinfect the surface, which will destroy bacteria and other microorganisms.
4. The fourth and final stage of cleaning is to dry the surface, and it’s recommended that you air dry where possible.
Therefore the prior process to cleaning is sanitizing the area for effective work.
