Multiple Choice

Why is protein considered an essential component of a healthy diet?

Proteins are not required in the diet because the body can synthesize all amino acids.

Proteins are the main molecules responsible for genetic information storage.

Proteins provide amino acids necessary for the synthesis and repair of body tissues.

Proteins are the primary source of long-term energy storage in the body.

Verified step by step guidance

Step 1: Begin by understanding the role of proteins in the body. Proteins are macromolecules made up of amino acids, which are the building blocks for various biological processes.

Step 2: Clarify the concept of essential amino acids. While the body can synthesize some amino acids (non-essential amino acids), there are others (essential amino acids) that must be obtained through the diet because the body cannot produce them.

Step 3: Explain the primary function of proteins in the body. Proteins are crucial for the synthesis and repair of tissues, including muscles, skin, and organs. They also play roles in enzyme activity, hormone production, and immune function.

Step 4: Address the incorrect statements in the problem. Proteins are not responsible for genetic information storage (this is the role of DNA and RNA), nor are they the primary source of long-term energy storage (this is the role of lipids).

Step 5: Conclude by emphasizing that proteins are essential in the diet because they provide the amino acids necessary for the synthesis and repair of body tissues, which is vital for maintaining overall health and functionality.
