Quizplus · Accepted Answer

Oxygen, hydrogen, and carbon make up more than 90% of a cell, with carbon being the backbone of all organic molecules, hydrogen being present in almost all molecules, and oxygen being necessary for aerobic cellular respiration. Potassium and sodium are important for cellular function, but their overall contribution to the cell's composition is much smaller.
