A suitable H/C ratio and the formation of macromolecular carbon clusters are essential factors for the synthesis of semi-graphite particles. The overgrowth of graphene and the aggregation of small molecules of PAHs in the low temperature region are favorable for the formation of carbon nanospheres....
2 Starch molecules are the main storage molecules in many types of cereal grain, such as the grain of the barley plant.(a)When the seed inside a barley grain germinates, genes coding for digestive enzymes are switched on. The enzymes that are synthesised catalyse the hydrolysis of storage mo...
What are the isomer structures of C_2Cl_3F_3? What type of compound is CH3-CH2-CH3? a) alkane b) branched alkane c) cycloalkane d) haloalkane e) isomer How many chiral carbon atoms does the following structure have? Which of the following molecules are structural isomers?
Total energy density of zinc carbon battery is 3.24 g/Ah + 1.21 g/Ah = 4.45 g/Ah =1 / 4.45 Ah/g = 0.224 Ah/g or 224 Ah/Kg. This is absolutely theoretical calculation, but in practice many other materials like, electrolyte, carbon black, water to be included in the battery, weight...
The present research evaluated ecosystem carbon storage, CO2 sequestration potential, and carbon credit valuation for major forests in the central Himalaya. By incorporating these findings into forest management plans and strategies, the carbon sequestration potential and carbon trading of the central ...
Learn the macromolecule definition and understand the different types of molecules. Study macromolecules examples, including industry and...
Themitochondriaorganelles are the cell's energy powerhouses. They break down the products of nutrients such as glucose into carbon dioxide and water while using up oxygen. They store the resulting energy in molecules ofadenosine triphosphate(ATP). The energy stored there powers cell activities. ...
According to a modern definition, carbohydrates are polyhydroxic aldehydes or ketones, which are substances with hydroxy (OH) and aldehyde (CHO) or ketone (C=O) functional groups [1]. Most carbohydrates consist of one or more sugar molecules, such as glucose or fructose [1]....
Tight junctions form a solid barrier to prevent movement of molecules between adjacent epithelial cells. Tight junctions are found in the simple columnar epithelium of the gut tube to regulate absorption of nutrients. Finally, gap junctions perform the opposite function. Gap junctions allow small molec...
Each of the types of reactions involves an overall energy change as well as the rearrangement of atoms/molecules. The rearrangement creates the products of the reaction. The product(s) are found to the right of the arrow in a chemical reaction formula. A chemical reaction occurs when a chemic...
