The correct choice highlights the action of hydrolysis on carbohydrates, particularly pointing out the breakdown of cellulose. Hydrolysis is a chemical reaction involving the addition of water to a substance, which leads to the breaking of chemical bonds. In the case of carbohydrates, hydrolysis can involve the breakdown of complex carbohydrates (like starch and cellulose) into simpler sugars (such as glucose).

When cellulose is hydrolyzed, the long chains of glucose units that compose cellulose are broken down into individual glucose molecules. This process is crucial because cellulose, being a polysaccharide, is generally insoluble in water, but when hydrolyzed, the resulting simpler sugars can often be more soluble. While the choice pertains specifically to cellulose, it illustrates how hydrolysis can change the structure and solubility characteristics of carbohydrates.

Understanding hydrolysis in this context is vital because it highlights how the physical and chemical properties of carbohydrates can be modified, affecting their interaction with water and ultimately their performance in food and beverage applications, such as brewing coffee.
