_ are biologically active proteins.
Correct answer: B. Enzymes
- A. Glycoproteins
- B. Enzymes
- C. Activators
- D. Inhibitors
Explanation
Biologically active refers to the substance having an effect on a living organism, tissue, or cell. Enzymes are biologically active proteins.Enzymes are specialized proteins that act as catalysts in biochemical reactions, speeding up the conversion of substrates into products. They play a crucial role in various biological processes by facilitating chemical reactions necessary for metabolism, growth, and other cellular functions. The other options, glycoproteins, activators, and inhibitors, may also be proteins, but they are not specifically defined as biologically active proteins like enzymes.

About Enzymes
Enzymes are biological catalysts that lower activation energy without being consumed, and their specificity is explained by the lock and key and induced fit models. Work includes the effects of temperature, pH and substrate concentration on reaction rate, plus competitive and non-competitive inhibition and how these differ.
