Biocatalytical proteins are_________________?
Correct answer: A. Enzymes
- A. Enzymes
- B. Substrate
- C. Lipids
- D. any of above
Explanation
Enzymes are biological catalysts, and most enzymes are proteins that speed up biochemical reactions without being consumed. A substrate is the substance acted upon by an enzyme, while lipids are not generally biocatalysts. Students may choose d by treating every biological substance as a possible enzyme, but the correct class here is enzymes.

About Enzymes as Biocatalysts
Enzymes are protein or RNA biocatalysts that lower activation energy without being consumed, and their active sites bind specific substrates. The topic covers the lock and key and induced fit models, effects of temperature, pH and substrate concentration, cofactors, enzyme specificity, and competitive versus non-competitive inhibition.
