 B. Glucose: Glucose is a carbohydrate used for energy, not for building hormones or hemoglobin.

C. Proteins: Hormones (such as insulin and growth hormone) and hemoglobin (which carries oxygen in red blood cells) are protein-based molecules essential for bodily functions.

D. Carbohydrates: Carbohydrates provide energy but do not contribute to the structure of proteins like hormones and hemoglobin.
