Which term describes proteins that provide all essential amino acids and are easy to digest and absorb?

• A. essential amino acids
• B. nonessential amino acids
• C. complete protein
• D. glycogen

Answer: (C)

Proteins vary in whether they supply every essential amino acid in the right amounts and how well the body can use them. A complete protein is one that provides all nine essential amino acids in sufficient quantities and is highly digestible, making it easy for the body to absorb and utilize. That’s why this term fits best: it describes a protein source that meets essential amino acid needs in a single, readily absorbed package. For contrast, essential amino acids are the amino acids we must obtain from foods, nonessential amino acids can be made by the body, and glycogen is a carbohydrate storage form, not a protein.
