Answer and Explanation:
Protein is one of the most important molecules in our organism, being present in the composition of all elements, in addition to participating in several metabolic processes. This importance creates the need to study this molecule, however, to study it it is necessary to know the composition chemistry and the levels of structure it presents.
The chemical composition of proteins is related to amino acids, since protein is formed by them. In this case, we can say that the proteins have the same composition as the amino acids containing carboxylic acid and different amino groups, which is what determines the name and function of the amino acid.
In addition to chemical composition, the structure levels of proteins are extremely important, as they only function at a specific structural level. As for these levels, proteins can have a primary structure (there are more than two amino acids organized in a linear row), a secondary structure (when the primary structure turns into a helix species), a tertiary structure (formed by a more intense folding of the secondary structure providing the appearance of helices and leaves) and quarternary structure (when several tertiary structures are joined, allowing folding at the three-dimensional level. This is the functional structure of the protein).
Human chorionic gonadotropin is secreted from the placenta. The correct option is D.
<h3>What is HCG?</h3>
HCG is known as Human Chorionic Gonadotropin.
It is a hormone secreted by the placenta during pregnancy.
The hormone specifically functions to thicken the wall of the uterus in order to be able to support the growing embryo.
It also signals to the body system to halt the process of menstruation.
