Lipids
Glucose
Proteins
Carbohydrates
The Correct Answer is C

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.

C. They give the body nonessential amino acids: Carbohydrates do not contribute to amino acid supply; nonessential amino acids can be synthesized by the body.
