Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What elements make up a protein?
A
CHO
B
CHON
C
CHON and sometimes S
D
CH
Explanation: 

Detailed explanation-1: -The acronym CHNOPS, which stands for carbon, hydrogen, nitrogen, oxygen, phosphorus, sulfur, represents the six most important chemical elements whose covalent combinations make up most biological molecules on Earth.

Detailed explanation-2: -Proteins are organic molecules composed of Carbon, Hydrogen, Oxygen, and Nitrogen (CHON). Proteins are created by linking together amino acids into protein links called polypeptide chains. Amino acids consist of the following elements: carbon, hydrogen, oxygen, nitrogen, and, sometimes, sulfur and selenium.

Detailed explanation-3: -Proteins are made of carbon, hydrogen, oxygen, and nitrogen (CHON). Nucleic acids such as DNA and RNA contain carbon, hydrogen, oxygen, nitrogen, and phosphorus (CHON P).

Detailed explanation-4: -Proteins are made of carbon, hydrogen, oxygen, nitrogen, & sometimes sulfur (CHONS).

Detailed explanation-5: -Proteins, carbohydrates and lipids are made from three basic molecules: carbon, hydrogen and oxygen. However, all proteins contain an element not found in carbohydrates and lipids is nitrogen. Nitrogen which is present in all amino acids (the building blocks that make up the protein chains).
