Hydrogen fuel cells power the shuttle's electrical systems, producing a clean byproduct-pure water, which the crew drinks. A fuel cell combines hydrogen and oxygen to produce electricity, heat, and water. Fuel cells are often compared to batteries. Both convert the energy produced by a chemical reaction into usable electric power. However, the fuel cell will produce electricity as long as fuel (hydrogen) is supplied, never losing its charge.
Chlorophyll b is a form of chlorophyll. Chlorophyll b helps in photosynthesis by absorbing light energy. It is more soluble than chlorophyll a in polar solvents because of its carbonyl group. Its color is yellow, and it primarily absorbs blue light.n land plants, the light-harvesting antennae around photosystem II contain the majority of chlorophyll b. Hence, in shade-adapted chloroplasts, which have an increased ratio of photosystem II to photosystem I, there is a lower ratio of chlorophyll a to chlorophyll b.
Chlorophyll is a blood builder and is also effective against anemia which is caused by the deficit of red blood cells in the body. Cancer: Chlorophyll is effective against cancer such as human colon cancer and stimulates the induction of apoptosis.lood clotting: Chlorophyll contains vitamin K which is vital for normal clotting of blood. It is used in naturopathy for the treatment of nose bleeds and for the females suffering from anemic conditions and heavy menstrual bleeding.
