Baby food manufacturers sometimes use proteases in their products. Proteases catalyze the breakdown of the proteins in these foods, making digestion easier for infants. Proteases are which of the following types of molecules?

• enzyme

• fatty acid

• carbohydrate

• nucleic acid

Which of the following molecules are an example of a nucleic acid?

Illustration 1 shows sugar that has formed a bond by the action of an enzyme. Illustration 2 shows the enzyme, and Illustration 3 shows the enzyme after the addition of heat.

How does the addition of heat affect the ability of an enzyme to help the sugar molecules form a bond?

• Heat allows the sugar molecules to bond more quickly.

• Heat provides places on the enzyme for other molecules to bond.

• Heat changes the enzyme so that the sugar molecules can no longer bond.

• Heat changes the chemical composition of the sugar molecules so they no longer need the enzyme.
