polymer to break it down into smaller pieces?
2. What is this called?
1. Primary energy source (glucose)
2. Structure (cellulose)
, 3. Short-term storage (starch, glycogen) - Answer-Q. How do carbohydrates function?
Amino Acid - Answer-Q. Identify this molecule.
Protein - Answer-Q. If you put many of these molecules together (by removing water),
what larger molecule will they form?
Proteins - Answer-Q. Which group of biomolecules function in building tissues, structure
maintenance, and repair?
Proteins - Answer-Q. Which group of biomolecules includes enzymes?
Muscle; Protein - Answer-Q. The "meat" you eat (beef, chicken, ham, etc) is actually
___ and therefore, which type of biomolecule?
Lipid - Answer-Q. This type of biomolecule is nonpolar; it does not dissolve in water.
