Enzymes are a form of which biomolecule?

• carbohydrates
• proteins
• nucleic acids
• lipids

Enzymes are polymers composed of which smaller subunits listed below?

• sugars
• nucleotides
• glycosides
• amino acids

Enzymes perform which of the following functions within living cells?

• inhibiting the translation of proteins
• providing structural stability
• transmitting ultraviolet rays
• catalyzing chemical reactions

Enzymes are known as biological catalysts because they -

• speed up chemical reactions
• slow down reaction rates
• increase the activation energy
• reduce the polarity of water
