Final answer:
The function not associated with proteins is genetic information storage. Proteins play various roles such as enzymes, structural support, and more, but DNA and RNA are responsible for storing and transferring genetic information.
Step-by-step explanation:
The function not represented by proteins in the body is D) Genetic information storage. Proteins serve numerous critical functions within the body, such as enzymatic catalysis, which relates to their role as enzymes speeding up chemical reactions. They are instrumental in structural support, contributing to cellular shape and composing bodily tissues like muscles. Moreover, proteins play roles in membrane structure, insulation, hormonal signaling, and as pigments. However, the storage and transfer of genetic information are exclusively the roles of nucleic acids like DNA and RNA, not proteins.
Enzymes as Proteins
Proteins that act as enzymes are vital for metabolism. They reduce the activation energy of chemical reactions, thus greatly accelerating them. It's important to note that enzymes are not consumed in the reactions they catalyze, are typically made from amino acids, and display a high degree of specificity towards their substrates.
