    Lipids are broken down for energy and are the major component of cell membranes. Many lipids also act as biological signal molecules.

    Proteins are generally thought of as structural molecules, although arguably proteins that act as enzymes to catalyze biological reactions are more important. They basically *do* everything that a cell needs to do.

    Nucleic acids encode the information required to produce proteins, which do the things that allow the cell to function.

    Carbohydrates are mostly broken down for energy.

    (This is obviously massively oversimplified. There are nucleic acid enzymes, carbohydrate attachments on proteins (producing glycoproteins for specific functions), and other exceptions, but in general the above is true.)

    you would be able to desire to probable discover the solutions with a seek engine. phosphate is a element of many organic and organic molecules. some examples are ATP, the skill source of maximum organic and organic mechanisms from automobiles to ion replace. phosphate is a element of the backbone that hyperlinks DNA nucleotides into chains. magnesium, i'm no longer as acquainted with. it fairly is a element of the electrolyte mileu that creates a stability between intracellular and extracellular cations and anions. i do undergo in strategies that chlorophyll incorporate magnesium interior the middle of its shape, form of like iron in hemoglobin.
