Question

Which of these organic molecules functions to help speed up biological chemical reactions? A) lipids Eliminate B) proteins C) nucleic acids D) carbohydrates

Answer 1

Answer is B) Proteins

Enzymes are the substances which help to speed up the biological chemical reactions by reducing the activation energy of the reaction. Enzymes are proteins. That's why we can get the answer as "B" among the given choices.

Answer 2

The answer would be:

B. Proteins

Enzymes act as catalysts in numerous biological chemical reactions. Most enzymes are PROTEIN molecules. As catalysts, enzymes speed up the biological chemical reactions by lowering the activation energy of the reaction. The fundamental role of proteins in living organisms is to act as enzymes.
