Either nitrogen, phosphorus, chlorine or potassium... I can't tell, but hope that helps:]
Better question. What cells do not contain proteins? Proteins is from the Greek and means " first place, " so I can not think of any cell without some types of proteins.
All living sources contain the element Carbon
Phosphorus complexes are present in proteins but is not present in sugars or fats..
All proteins contain carbon, oxygen, hydrogen and nitrogen. Some also contain sulphur in the amino acids Methionine and Cysteine.
All cells contain proteins.
Proteins contain nitrogen, which is not present in carbohydrates.
All proteins contain carbon, hydrogen, nitrogen, and oxygen. Many also contain sulfur, and cofactors can have all kinds of wacky stuff in them, like iron, manganese, cobalt, you name it.
Elements are pure substances, consisting of atoms. They do not contain proteins. Proteins are molecules consisting of a chain of atoms.
Nitrgen. The all have the elements Carbon, Hydrogen and Oxygen in common, but on top of that, proteins ALSO contain nitrogen.
Proteins contain carbon, hydrogen, oxygen, and nitrogen.
Nitrogen is a key element. Proteins contain nitrogen and without nitrogen no protein.
Nitrogen is the element present in all proteins except carbohydrates and fats. Amino acids make up all proteins, and they contain the amino group NH2, except for carbohydrates and fats.?æ
Better question. What cells do not contain proteins? Proteins is from the Greek and means " first place, " so I can not think of any cell without some types of proteins.
All living sources contain the element Carbon
They all contain acid and bases
Carbon is considered the building block of life and makes up macromolecules. Nitrogen, oxygen and hydrogen are the other 3 key building blocks.
There are several elements in all proteins and all nucleic acids:Hydrogen,Carbon,Oxygen, andNitrogen.All nucleic acids also contain a lot of phosphorus and commonly proteins contain a tiny bit too, but that is not really relevant to the intention of the question.
