Potential energy  is the energy that matter possesses because of its location or structure. Chemical energy  is a form of potential energy stored in molecules because of the  arrangement of their atoms. Energy can be converted from one form to another. For example, as a boy climbs stairs to a diving platform, he is releasing chemical energy  stored in his cells from the food he ate for lunch. The kinetic energy of his muscle movement is converted into potential energy as he climbs  higher. As he dives, the potential energy is converted back to kinetic energy. Kinetic energy is transferred to the water as he enters it. Some energy is converted to heat due to friction. The localization of enzymes within a cell helps order metabolism.

Unformatted text preview: Structures within the cell help bring order to metabolic pathways. A team of enzymes for several steps of a metabolic pathway may be assembled as a multienzyme complex. The product from the first reaction can then pass quickly to the next enzyme until the final product is released. Some enzymes and enzyme complexes have fixed locations within the cells as structural components of particular membranes. Others are confined within membrane-enclosed eukaryotic organelles. Metabolism, the intersecting set of chemical pathways characteristic of life, is a choreographed interplay of thousands of different kinds of cellular molecules....
