Final answer:
Fifth-generation carpets are capable of repelling all types of stains, which include food, liquid, and pet stains. They utilize enzymes, like proteases, lipases, a-amylases, and cellulases, to break down the various molecular structures of stains, making them easier to clean.
Step-by-step explanation:
Fifth-generation carpets are designed to repel different types of stains by using advanced technology, including specialty treatments and engineered fibers. These carpets are known for their ability to resist and repel all types of stains, including food stains, liquid stains, and pet stains.
To address various stains, specific enzymes such as proteases (savinase) for proteins, lipases for greases, a-amylases for carbohydrates, and cellulases for cellulose are required to break down stubborn stains that are commonly encountered in households. These enzymes degrade stains by breaking down their molecular structure, making them easier to remove from carpet fibers. Ultimately, the science behind these fifth-generation carpets is similar to the process of using different enzymes to treat specific stains.
