Question

Design a meal that contains all four major macromolecules you learned about. Explain how each macromolecule is present in the foods you have selected and explain their role in the body.

A) Carbohydrates: Pasta, Proteins: Chicken, Lipids: Avocado, Nucleic Acids: Spinach
B) Carbohydrates: Bread, Proteins: Fish, Lipids: Olive oil, Nucleic Acids: Tomatoes
C) Carbohydrates: Rice, Proteins: Beans, Lipids: Butter, Nucleic Acids: Lettuce
D) Carbohydrates: Potatoes, Proteins: Beef, Lipids: Cheese, Nucleic Acids: Carrots

Answer 1

Option B provides a meal that includes bread as a carbohydrate source, fish for protein, olive oil for lipids, and tomatoes for nucleic acids, ensuring all four major macromolecules are present for a balanced diet.

Step-by-step explanation:

Designing a Meal with All Four Major Macromolecules

When designing a meal that contains all four major macromolecules, it is important to choose foods that embody each category. Here is an explanation of how each macromolecule is present in the foods from option B and their role in the body:

• Carbohydrates: Bread provides a rich source of carbohydrates, which are the body's primary source of energy. They are broken down into glucose, used for immediate energy, or stored as glycogen for later use.
• Proteins: Fish is an excellent source of protein, which is necessary for the building and repair of body tissues, including muscle and bone. Proteins are composed of amino acids, which are the building blocks for many structures in the body.
• Lipids: Olive oil contains lipids, which are fats that serve as a secondary source of energy, are crucial for cell membrane structure, and aid in the absorption of fat-soluble vitamins.
• Nucleic Acids: Tomatoes have nucleic acids like DNA and RNA, which contain the genetic information required for cell function and heredity.

These four macromolecules are essential for various bodily functions and are the foundation of a well-balanced diet.
