Answer;
ATP
Organisms use energy to drive chemical reactions which is ATP.
Explanation;
- ATP is the usable form of energy that is used by the cell to drive cellular processes such as transport, growth and development, among other activities by the cell.
- ATP is produced by cellular respiration which takes place in the mitochondria. During cellular respiration simple sugars are broken down in three phases, glycolysis, Kreb's cycle and electron transport chain, to release ATP molecules, which can be used by the cell or stored for future use.
