In a tropic level 10% of the energy is lost as heat for cellular respiration but, I was confused on weather it has something to do with the cell. So if you have any idea on what happens during this in a cell please let me know. Thanks.
Energy is not a physical unit. It is a philosophical concept and an accounting technique used to analyze mechanical and chemical exchanges. In nuclear physics it is defined as a wavelength of light, in biology it is a synonym for metabolism, and in public utilities they say energy when they mean connectivity. Anybody who uses the word in any other context either does not know what he is talking about, or is peddling something you don't need.
In respiration, the chlorophyll absorbs red light and that cools the area because the light would otherwise have been converted to heat. But it maybe does not absorb all, and someone estimated that 10% of the power in the light was converted to heat without contributing to photosynthesis. This topic deals with a lot of things that are not known, but scientists pretend to know them and you just have to go along with them.
The link between matter and energy explains the power of the sun, which keeps us alive and well. The above has been said of energy and matter. “Matter is simply one form of energy,” Scientific American noted. This relationship between matter and energy was expressed by Einstein’s famous formula E=mc2 (energy equals mass times the speed of light squared). This equation reveals that a little mass, or matter, harbors unbelievable energy
From where, though, did the matter and the energy needed for such a “transformation” originate? Science has no satisfying answer. Interestingly, the Bible says of God: “Due to the abundance of dynamic energy, he also being vigorous in power, not one of them [the heavenly bodies] is missing.” (Isaiah 40:26) Whatever means God used to create the universe, he clearly has the energy and the power needed to do so.

How do molecules and energy move within a cell? The Times of London reports that four American neurobiologists recently demonstrated “that packets of molecules, and the cell’s energy sources, the mitochondria, manœuvre rapidly along threads called ‘microtubules’, attaching and re-attaching, and shifting from thread to thread like monkeys in the forest.” The microtubules, which are made of small protein subunits, assemble and disassemble according to the needs of the cell. The life of various cells differs. For instance, white blood cells live about 13 days, red blood cells about 120 days.
Enlightening as these discoveries are, the scientists cannot explain what makes it all work. The Bible psalmist said to God: “I shall laud you because in a fear-inspiring way I am wonderfully made.” (Ps. 139:14) Yes, God has equipped man with a wonderfully unique combination of brain and body. He has designed humans to live forever here on earth.

Hydroelectric power plants already supply over 6 percent of the world’s energy needs. According to the International Energy Outlook 2003 report, over the next two decades, “much of the growth in renewable energy sources will result from large-scale hydroelectric power projects in the developing world.
A fuel cell is a device that produces electricity from hydrogen—not by burning it, but by combining it with oxygen during a controlled chemical reaction. When pure hydrogen is used rather than a hydrogen-rich fossil fuel, the only by-products of the reaction are heat and water
Today, fuel cells are being developed to replace the internal combustion engine in motor vehicles, to provide electricity for commercial and domestic buildings, and to power small electric devices, such as mobile phones and computers.
