For proper functioning, a protein should have its amino acids in:
Correct answer: C. A specific arrangement
- A. A random arrangement
- B. A specific medium
- C. A specific arrangement
- D. Ascending order
Explanation
The correct answer is that a protein should have its amino acids in a specific arrangement for proper functioning. This sequence is determined by the gene encoding the protein and dictates the protein's folding into its functional three-dimensional structure. This specific conformation is vital for the protein's interactions and biological activity. A random arrangement would disrupt the structure, leading to loss of function. While the medium can influence protein activity, it does not replace the need for a specific sequence. An ascending order is irrelevant to protein functionality and lacks biological significance in this context.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
