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.
Hence this process of glucose synthesis is called as photosynthesis. The glucose that is synthesized through the photosynthetic process helps in the growth of the plant. Chlorophyll is an important molecule in the plants which act as photoreceptor.It effectively absorbs the sunlight and transfers it to the electron transporting molecules and in turn reduces the ADP and NADP molecules into energy molecules. Chlorophyll consists of chlorophyll-a and chlorophyll-b.This molecule exists in the plant along with proteins. Chlorophyll exists as photosystem-I and photosystem-II based on the wavelength of light that each of them is able to absorb. The wavelengths that are absorbed by these photosystems are 700nm and 680nm.ence this process of glucose synthesis is called as photosynthesis. The glucose that is synthesized through the photosynthetic process helps in the growth of the plant. Chlorophyll is an important molecule in the plants which act as photoreceptor.
