How is energy stored in the form of ATP? |
|
Answer» ? \tThe energy produced during respiration is stored in the form of ATP molecules in the cells of the body and used by the organism as when required.\tADP (Adenosine Di-Phosphate, low energy content), Inorganic Phosphate (Pi) and ATP (Adenosine Tri-Phosphate, high energy content) are the substances present inside a cell.\tThe energy released during respiration is used to make ATP molecules form ADP and inorganic phosphate.\tADP + Phosphate + Energy → ATP\t(Low energy) (For respiration) (High energy)\tThus, energy is stored in the form of ATP.\tWhen the cell needs energy, then ATP can be broken down using water to release energy. Thus:\tATP → ADP + Phosphate + Energy\tThe energy equivalent to 30.5KJ/mole is released in this process.\tATP is known as energy currency of cells. ADP molecule reacts with inorganic phosphate,with the help of energy produced in our body in mitochondria to form ATP molecule. When body needs energy ATP breaks down into inorganic phosphate and ADP relasing the energy.. |

Chemical properties of carbon compound |
|
Answer» \tAll the allotropic forms of carbon burn in the presence of oxygen releasing carbon dioxide along with heat and light.\tC + O2 → CO2 + heat and light\tSaturated hydrocarbons undergo combustion giving a clean flame. But in the presence of limited supply of air hydrocarbons produces a sooty flame as a result of incomplete combustion.\tCarbon compounds gets readily oxidised on combustion. The following equation shows the conversion of alcohols to carboxylic acid. By lossing for electron in outer orbit it would required large amount of energy |
