Which combining form indicates relationship to sugar or glycerol?
Correct Answer:
Glyc/o
Explanation:
Understanding combining forms means linking them to their most common meanings. The form glyc/o signals sugar or sweetness. It comes from a word root meaning sweet and appears in many terms tied to sugar, like glycogen (a sugar storage molecule), glycolysis (sugar breakdown), and glycemia (blood sugar). The other roots here point to stone, sweat, or tears, which don’t relate to sugar. If glycerol-specific terminology were in play, glycer/o would be used, but for sugar-related terms, glyc/o is the standard. That makes glyc/o the best fit.
