Most plant-based foods, such as oatmeal and beans, contain both soluble and insoluble fiber. However, the amount of each type varies in different plant foods. To receive the greatest health benefit, eat a wide variety of high-fiber foods.
A galvanic cell is a device in which a spontaneous oxidation-reduction reaction is used to convert chemical energy into electrical energy. Galvanic cells harness the electrical energy available from the electron transfer in a redox reaction to perform useful electrical work.
When electrical energy is added to the system, the chemical energy is increased. Similarly to a galvanic cell, electrolytic cells usually consist of two half cells. Important examples of electrolysis are the decomposition of water into hydrogen and oxygen, and bauxite into aluminium and other chemicals.
