Question

organic macromolecules worksheet

1. name an important role in carbohydrates.
2. what is a polysaccharide?
3. what is the most common monosaccharide?
4. what elements are carbohydrates composed of?
5. what are two functions of lipids?
6. name three examples of lipids.
7. list one biological function of a protein.
8. what elements make up nucleotides?
9. what groups are included in an amino acid?
10. what are the three parts of dna?

Explanation:

1. Carbohydrates are a primary energy - source for cells.
2. A polysaccharide is a long - chain carbohydrate made of many monosaccharides linked together.
3. Glucose is the most common monosaccharide.
4. Carbohydrates are composed of carbon, hydrogen, and oxygen.
5. Lipids function as energy storage and as components of cell membranes.
6. Examples of lipids include fats, oils, and phospholipids.
7. Proteins can act as enzymes to catalyze biochemical reactions.
8. Nucleotides are made up of a nitrogen - containing base, a five - carbon sugar, and a phosphate group.
9. An amino acid contains an amino group, a carboxyl group, and a side chain (R - group).
10. The three parts of DNA are deoxyribose sugar, phosphate groups, and nitrogenous bases.
