Answer:
According to the levels of organization in the body, the level of organization in which proteins, like collagen, are found is the molecular level, allowing the structural support and the performance of other essential functions.
Explanation:
Proteins are biological macromolecules, polymers of units called amino acids. These molecules belong to the molecular level of organization in living organisms.
The level of organization where proteins are found allows them:
- <em>Form an essential part of cells.</em>
- <em>Contribute to the construction of tissues and organs.</em>
- <em>Participate in metabolic reactions, as enzymes. </em>
- <em>Defense of the organism, in the form of antibodies.</em>
- <em>Regulation of vital functions, forming hormones.</em>
Other functions of proteins are to integrate the cell membranes and perform transport function, to form receptors and to be an energy reserve.
