Benji is a show dog who needs a fancy and expensive dogfood fortified with macromolecules to help him maintain a glossy coat, strong muscles, an adequate supply of amino acids, and support for cell membrane formation.
Which macromolecules should you be looking for in the kibble (dogfood) ingredients?
a
Lipids and nucleic acids
b
Nucleic acids and carbohydrates
c
Proteins and lipids
d
Carbohydrates and proteins
I would go with c.
In order to determine which macromolecules should be present in the dog food to meet the specific needs of Benji the show dog, we need to understand the functions of different macromolecules and their roles in the body.
Macromolecules are large molecules composed of smaller subunits. The four main types of macromolecules are lipids, nucleic acids, carbohydrates, and proteins. Each of them plays a unique role in the body's functions.
Lipids primarily function as a source of energy and insulation. They also contribute to cell membrane formation and the production of hormones. However, lipids do not directly support muscle development, amino acid supply, or cell membrane formation, which are Benji's specific requirements.
Nucleic acids, including DNA and RNA, are responsible for storing and transmitting genetic information. They are not directly involved in the maintenance of a glossy coat, strong muscles, amino acid supply, or cell membrane formation. While nucleic acids contain important information for overall health, they are not the primary macromolecules needed for Benji's specific requirements.
Carbohydrates serve as an energy source, providing quick and readily available fuel for the body. They support muscle function and play a role in cell membrane formation. However, carbohydrates alone are not sufficient to meet all of Benji's needs, as they do not provide amino acids or directly contribute to a glossy coat.
Proteins, on the other hand, are essential for muscle development and repair. They also provide amino acids, which are the building blocks for many important molecules in the body. Proteins are crucial for a glossy coat, as they contribute to hair structure. Additionally, they play a role in the formation of cell membranes. Therefore, the correct answer is option c: Proteins and lipids.
To meet the specific requirements of Benji, you should look for dog food ingredients that contain proteins and lipids, along with other necessary nutrients. It is advisable to consult with a veterinarian to ensure that Benji's diet is properly balanced and tailored to his unique needs.
