C. Shale

<h2>Protein folding </h2>
Explanation:
- Molecular chaperones bind to nascent and folding or misfolded proteins (through improperly exposed hydrophobic regions) and stabilize the polypeptide so it can fold into its native state
- They have the ability to prevent non-specific aggregation by binding to non-native proteins
- They play an important role in protecting cells from being damaged under environmental stress, such as extreme heat, poisoning, or mental stress
- Most common chaperones are heat shock proteins which are also called stress proteins
- The intracellular folding environment for proteins is chaotic because of the presence of other biomolecules, folding proteins, improper or fluctuating pH, heat, and other denaturants
- Chaperonins provide actual chambers for misfolded proteins to properly refold, segregating the protein from the chaotic cellular environment.
- The main key function of chaperonins is to assist in the folding of large protein molecules
It would be B) Pro
Hope this helps you :))
Protozoa are single-celled eukaryotic organisms. Many aquatic animals feed on protozoa. Protozoa help control the population of bacteria as well as other protozoans by feeding on them. Controlling the population of other organisms is important in maintaining ecological balance and diversity.
