Which statement is true about enzymes?

Which statement is true about enzymes?

• A. They are inorganic minerals
• B. They are lipids storing energy
• C. They are biological catalysts (correct)
• D. They are formed from nucleotides

Answer: (C)

Enzymes are biological catalysts that speed up chemical reactions by lowering the activation energy required for the reaction to proceed. Most enzymes are proteins with specific shapes and an active site where a substrate binds, bringing reactive groups into the right orientation to make the reaction happen more quickly. They are not consumed in the process and can be reused. This makes the statement true: enzymes accelerate reactions rather than acting as minerals or storage lipids, and they’re not simply formed from nucleotides (the classic enzymes are proteins, though some RNA molecules can also act as catalysts in special cases).
