Enzyme Review

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

What is the name of the molecule or substance that the enzyme reacts with?

• Substrate

• Active site

• Inhibitor

• Product

Where does the reaction between the enzyme and the substrate take place at?

• Substrate

• Inhibitor

• Active site

• Product

The new molecules or substances released by the enzyme are called:

• Substrate

• Active Site

• Inhibitor

• Product

This diagram shows the biochemical pathway that produces arginine in Neurospora, a

mold. Neurospora is easily grown on a simple jelly-like medium.

If Enzyme X were not functioning properly, what substance would need to be added to the growth medium for this mold to grow normally?

• Base Substance

• Ornithine

• Enzyme Y

• Enzyme Z

Neurospora requires three different enzymes to complete this biochemical pathway because each enzyme –

• is made from amino acids

• can only be used a single time

• is specific to a single substrate

• creates the same compound
