Question

which of these is one function of proteins?

perform chemical reactions throughout the cell.
storage of genetic code
main energy source for living things
long-term energy storage

Explanation:

Analyze the functions of biomolecules

• Perform chemical reactions throughout the cell: This is a primary function of proteins, specifically enzymes, which catalyze biochemical reactions.
• Storage of genetic code: This is the function of nucleic acids (DNA and RNA).
• Main energy source for living things: This is the primary function of carbohydrates (like glucose).
• Long-term energy storage: This is the primary function of lipids (fats).

Identify the correct option

• The option "Perform chemical reactions throughout the cell" correctly describes a major function of proteins.

Answer:

• (A) Perform chemical reactions throughout the cell. (Correct answer)
• (B) storage of genetic code
• (C) main energy source for living things
• (D) long-term energy storage
