Which elements are present in all living things?

Answer 1

Carbon and hydrogen are the only elements in allmolecules in living things.

After that come oxygen and nitrogen, but these are not in all molecules in living things.

All living cells and organic compounds are made of carbon, hydrogen, and oxygen. This includes all protiens, fats and carbohydrates that we consume as nutrients.

Hydrocarbons are made of Carbon and Hydrogen. This includes products such as fuel oil, methane, ethane, butane, benzene, paraffin; all of which can be burn for fuel.

Answer 2

In order of abundance, the three most abundant elements in the human body are oxygen, carbon, and hydrogen. Oxygen is the last electron acceptor in aerobic cellular respiration, without which, aerobic respiration would be impossible. The three elements together make up many of the biomolecules needed for life, such as carbohydrates, triglycerides, cholesterol, vitamin C, vitamin D, and sex hormones.

Answer 3

Oxygen, Carbon, Nitrogen, and Hydrogen. There are four.

Answer 4

I believe carbon is the element that is in all living things and living cells, as oxygen isn't always in all living things, and all life that we currently know of is carbon-based.

Answer 5

Carbon, hydrogen, oxygen and nitrogen. There are four in all.

Answer 6

There is actually 4 elements. Carbon, Hydrogen, Oxygen and Nitrogen

Answer 7

Remember the acronym CHONPS: In order from most common to least common: Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorous, and Sulphur.

Answer 8

The elements found in all living things are carbon, hydrogen, nitrogen, oxygen, phosphors, and sulfur. I use CHNOPS to remember these.

Answer 9

Oxygen, Hydrogen, and Carbon.

Answer 10

Carbon, oxygen, hydrogen
