Question #7680a

Answer 1

catalysts

Explanation:

both amylase and protease are enzymes.

each type of enzyme is shaped so that a specific type of molecule (substrate) can fit into its active site. (e.g. amylase is specific to starch, as protease is to protein)

enzymes work to break down large molecules into smaller ones, so that they can be absorbed into the bloodstream and used by the body. (e.g. amylase breaks down starch into glucose, protease breaks down proteins into amino acids)

here, an enzyme is shown to hold two substrates.

these substrates react in the enzyme's active site, and are released as products.

with the enzyme present, less energy is needed for the reaction between the substrates to start. this means that the reaction can happen in a shorter time.

enzymes are not consumed in this process, and keep working for as long as the substrate is present.

because enzymes decrease time of reaction (therefore increasing overall speed) and are not used up while this happens, they are known as catalysts.
