Which of the following elements is present in protein?*1 pointoxygenNitrogencarbonOption 5hydrogen

To determine which elements are present in proteins, we can analyze the composition of protein molecules.

Elements Present in Proteins

1. Oxygen: Proteins contain oxygen as part of their molecular structure, particularly in functional groups.
2. Nitrogen: Nitrogen is a crucial component of amino acids, the building blocks of proteins.
3. Carbon: Carbon atoms form the backbone of protein structures, as they are part of amino acids.
4. Hydrogen: Hydrogen atoms are also found in amino acids and are bonded to carbon and nitrogen.

Summary

Proteins are made up of a combination of these elements. Therefore, the correct answer is that all of the options listed (oxygen, nitrogen, carbon, hydrogen) are elements found in proteins.
