Yes, glucose is indeed a monomer. Specifically, it is classified as a monosaccharide, which is the simplest form of carbohydrates. Monosaccharides are the building blocks of more complex carbohydrates, known as polysaccharides.
Glucose plays a crucial role in biology as it serves as an essential energy source for cells. When multiple glucose molecules bond together, they form polysaccharides such as starch and cellulose, which are important for energy storage and structural support in plants.
In summary, glucose is a fundamental monomer, and understanding its role helps us grasp larger concepts regarding carbohydrates and energy metabolism in living organisms.
