Question

Which of the following statements about proteins is false? a. proteins are composed of amino acids b. different proteins are different due to different combinations of amino acids used in each type of protein c. dietary protein from animal sources better matches the amino acid needs of humans compared to dietary protein derived from plants sources d. proteins are made of amino acids, vitamins, and minerals

Answer 1

Answer: d. proteins are made of amino acids, vitamins, and minerals

Proteins are biomolecules that are found in all living things. They are made up of long chains of amino acids. The long chain exhibit specific amino acids,  which makes up a typical protein molecule. Hence, proteins can be distinguished based upon the amino acid composition. Vitamins and minerals are not the components of proteins because they are another class of biomolecules.  

Answer 2

The statement that "proteins are made of amino acids, vitamins, and minerals" is false.

WHAT ARE PROTEINS:

• Proteins are one of the biological molecules in nature. They are polymeric compounds made up of monomers called AMINO ACIDS.

• Proteins contain a large chain of amino acids linked together by a covalent bond called peptide bond. Proteins are different because they contain different combinations of amino acids in their structure.

• Dietary protein from animal sources better matches the amino acid needs of humans compared to dietary protein derived from plants sources because humans are more related to animals.

Therefore, it is false that proteins are made of amino acids, vitamins, and minerals.
