This view represents these molecules simply as hydrated Like amylose, cellulose is a linear polymer of glucose. WebTrue or false? However, certain microorganisms can digest cellulose because they make the enzyme cellulase, which catalyzes the hydrolysis of cellulose. Monosaccharides are classified based on the number of carbons the molecule as trioses (3 C), tetroses (4 C), pentoses (5 C), and hexoses (6 C). Some sugars, such as sucrose, or table sugar, consist of two monosaccharides and are called disaccharides. starch. Complex carbohydrates, or polysaccharides, consist of hundreds or even thousands of monosaccharides. A molecule that combines protein and carbohydrate.
