Which term is represented by the root "glyc/o"?

The root "glyc/o" is derived from the Greek word "glykys," which means "sweet." In medical terminology, this root pertains specifically to substances that are related to sugars, particularly glucose. Thus, it serves as a prefix in various terms associated with sugar and its metabolic processes.

While glucose is a specific type of sugar, the term "sugar" encompasses a broader category that includes various forms of carbohydrates that can contribute to sweetness. This broader interpretation aligns with the general meaning of "glyc/o," solidifying why "sugar" is the best choice among the options provided. The other terms—granules and glomerulus—do not relate to sugars or sweet substances, making them less relevant to the question at hand.
