Question

question 1 - 9
which statement correctly describes a property of enzymes?
enzymes react at identical rates under all circumstances.
enzymes are destroyed and then reformed after each reaction.
enzymes form permanent structures when they bind to substrates.
enzyme structures are specific to the type of substrate they bond to.

Explanation:

Enzyme - substrate binding is highly specific due to the enzyme's active - site shape and chemical properties. Enzyme reaction rates vary with factors like temperature and pH. Enzymes are not destroyed in reactions and do not form permanent structures with substrates.

Answer:

Enzyme structures are specific to the type of substrate they bond to.
