Answer:
The correct answer is the number 1) It may be an essentially random process
Explanation:
Protein folding is a chemical process in which the structure of a protein assumes its functional configuration.
All protein molecules are heterogeneous, unbranched chains of amino acids. By folding and rolling to take a specific three-dimensional shape, proteins are able to perform their biological function.
The opposite process is called denaturation, in which an original protein is forced to lose its functional configuration, becoming an amorphous and non-functional chain of amino acids. Denatured proteins can lose their solubility and precipitate into insoluble solids. In some cases, the denaturation is reversible and the proteins may reenact. However, denaturation is, in most cases, an irreversible process.
In certain solutions and under certain conditions, proteins may not fold. Temperatures above or below the range in which cells usually survive, cause the protein to unfold or denature (this is why boiling causes the egg white to become opaque). High concentrations of solute and pH extremes can lead to the same result. A completely denatured protein has no tertiary and secondary structures, and exists under the designation of a random spiral. Cells sometimes protect their proteins from denaturation by heat thanks to enzymes known as companions or heat shock proteins, these help other proteins, both to fold and to stay folded. Some proteins never fold inside cells except with the help of accompanying molecules, which isolate individual proteins so that their folding is not interrupted by interactions with other proteins. The DNA configuration is maintained by another set of enzymes.
The statement concerning the process of spontaneous folding of proteins that is false is A. It may be an essentially random process.
Protein folding simply means the chemical process where the structure of a protein gets its functional configuration. The process of spontaneous folding of proteins can be may be defective in some human diseases.
The process of spontaneous folding of proteins may involve an initial formation of local secondary structure and an initial formation of a highly compact state.
In conclusion, the false statement is it can be an essentially random process.
