In order to be carried in the chylomicron, retinol (once in the enterocyte) is esterified by lecithin retinol acyl transferase.
All-trans-retinol is referred to as vitamin A, when a fatty acyl group is esterified to the hydroxyl terminus of retinol, a storage form of retinol, the retinyl ester, is formed. In tissues, retinal serves as an intermediate in the synthesis of retinoic acid from retinol.

Answer:</h2>
<u>reactants, </u> <u>products</u>
<u>catalyst</u>
<u>activation energy</u>
<u>enzymes</u>
<h2>
Explanation:</h2>
Chemical reactions convert <u>reactants</u> to <u>products</u>. In nonliving systems, the presence of a(n) <u>catalyst </u>allows the reaction to proceed very quickly and have a lower <u>activation energy</u>. In living systems, this function is carried out by proteins called <u>enzymes</u>.
10. before replication begins, the strands of DNA are separated and used as templates for the new strands. the replication process creates 2 identical double helixes, each has 1 new strand and 1 old one.
11. without dna replication, damaged cells could not be replaced/repaired and cells need dna, cells would become mutated without dna replication.
12. mutations are rare because dna polymerase proofreads the strands but if the process occurred incorrectly and was not corrected by the polymerase, the cell would become mutated and could be really harmful.

D, light can travel in the air or a vacuum and the speed is constant whether the light source is stationary or moving.
