2. the marbling, or fat, in a piece of steak is made up of
3. complex are found in potatoes and pasta.
4. dna and rna are and can be found in all living things.
5. lean meats and soy - based food have high amounts of

part 5 - macromolecule functions - fill in the chart with the macromolecules function.
part 6 - what elements? - circle the elements that make up each macromolecule.

Explanation:

1. Soft drinks like Coca - Cola have many simple carbohydrates (sugars are simple carbohydrates) added to them.
2. The marbling (fat) in a steak is made up of lipids (fats are a type of lipid).
3. Complex carbohydrates (starch in potatoes and pasta is a complex carbohydrate) are found in potatoes and pasta.
4. DNA and RNA are nucleic acids (they are the two main types of nucleic acids).
5. Lean meats and soy - based food have high amounts of proteins (these are common protein - rich foods).

For the macromolecule functions:

• Carbohydrate: Main source of energy for the body.
• Lipids: Store energy, insulate the body, and make up cell membranes.
• Protein: Build and repair tissues, act as enzymes and hormones.
• Nucleic Acids: Store and transmit genetic information.

Answer:

1. Carbohydrates
2. Lipids
3. Carbohydrates
4. Nucleic Acids
5. Proteins

Macromolecule Functions:

• Carbohydrate: Main energy source.
• Lipids: Energy storage, insulation, cell - membrane component.
• Protein: Tissue building/repair, enzymatic and hormonal roles.
• Nucleic Acids: Genetic information storage/transmission.
