A protein that supplies all the essential amino acids is considered a:

A protein that supplies all the essential amino acids is classified as a complete protein. Essential amino acids are those that cannot be synthesized by the body and must be obtained through the diet. Complete proteins contain adequate proportions of all nine essential amino acids necessary for human nutrition. This type of protein is typically found in animal sources such as meat, dairy products, and eggs, as well as in some plant sources like quinoa and soy.

In contrast, incomplete proteins lack one or more of the essential amino acids, while the term "partial protein" is not commonly used in nutritional science. "Complex protein" might imply a more intricate structure or a combination of protein types but does not specifically denote the completeness of the amino acid profile. Therefore, the classification of a protein as complete is specifically due to its ability to meet all the essential amino acid requirements of the body.
