Ui do not known man just trying to answer my first question

Ithink it’s c or b for the answer.

Mitochondria produce atp, a high energy compound. atp is used for all sorts of enzyme-mediated reactions, such as making proteins/nucleotides/etc, certain compounds cross the cell membrane, muscles move, etc.  without this source of energy, a cell will die. it will not be able to repair itself, defend against pathogens, etc.

Lipid because of the high percentage of carbon to carbon bonds, which store more energy than other bonds.
