Assuming eukaryotic cells:
o phospholipids from the membranes of organelles and from the endoplasmic reticulum - treat with detergents to break up membranes and solubilize the phospholipids
o proteins, from the cytosol, from the organelles, and bound to the DNA - treat with proteases (such as those found in pineapple juice) to break them up into small pieces and amino acids
o RNA, found in the nucleus and in the cytosol and in the ribosomes. -- Treat with RNAases to break these up.
