I've stuck at this question for half an hour now. All my book talks about is organic molecules and other stuff, but no inorganic molecules. It's part of my biology homework. And don't say to look for it myself. I've searched the internet, looked in my mom's college biology books but could not find anything! Please help!

1. Oxygen molecules. Used in energy reactions and a major component of organic cell parts.
2. Na (sodium) needed by the cell to maintain water balance and used by nerve cells in communication with the rest of the organism.
3. Phosphorus (P) used in energy reactions and a major component of the cell's DNA.
4. Potassium (K) used by the cell to maintain water balance, nerve cells to transmit impulses

Well,
Zinc is essential for many enzymes. Manganese too. Copper is also needed for a few rather relativley unknown enzymes. Selenium is also an essential cofactor for a few enzymes.
Aside from enzyme cofactors, you could include iron (hemoglobin), hydroxyapatite (tecnhically mineral)
