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 chemical compound that collects light and uses the light to make energy in plants. Additionally, chlorophyll gives plants their green color.ccording to âEncyclopedia of Natural Medicine,â liquid chlorophyll can increase the quality and quantity of your red blood cells because the compound has a chemical composition very similar to hemoglobin. Hemoglobin is a molecule found in your red blood cells responsible for transporting oxygen.
