Which combining form means glucose?

Which combining form means glucose?

• A. Lys/o
• B. Dia-
• C. Opt/o
• D. Gluc/o

Answer: (D)

Understanding how combining forms connect to substances helps you read medical terms more accurately. The combining form for glucose is gluc/o. It signals that the term involves glucose or glucose-related processes, and you’ll see it in words like glucogenesis or glucose itself when formed with a suffix. The other forms point to different ideas: lys/o means destruction or breakdown (as in lysis), opt/o relates to vision or sight, and dia- is a prefix meaning through or across. So gluc/o is the correct choice because it directly names glucose.
