Thanks for directing my attention to photosynthesis. It has led to enourmous amount of interesting stuff. In order to avoid cluttering this forum I have dumped various links and related comments to a pdf file for anybody interested to see. The exact nature of energy seems to be very elusive. Add quantum entanglement to it and and there is so far no explanation. Flipping a distant particle lightyears away needs instant transfer of energy. Hopefully future research on black energy together with Dr. Campbell's meta-space will help find some hint to answer the question what energy is exactly.

Hit on head from parallel universe? Parallel universes have been turned down before on this forum. Here is a different, rather radical approach. How many times have I heard on TV that there could be a parallel universe only inches from us. I would always like to ask the lecturer how comes a carpenter in such close parallel universe, carrying a 2x4, does not hit me on head when turning around. So what is a universe exactly? Surfing for a definition found a great variety of them. Most loaded with lots of gobbledygook. IMO definition of a universe should be: It must have 3 linear spatial dimensions xyz. Throw in time and any number of hidden dimensions to keep the physicists happy. That's it. No more, no less. There are no floating branes like flying carpets carrying parallel universes. There is no proof for that. I have plenty of proof for xyz universe because I LIVE IN IT! So do you. Does this make any sense? Or not?

Ronald Hyde Thanks for your reply. For not being a biochemist, the Wikipedia link is well over my head. It just seems to confirm that energy enables chemical reactions. Back to basics: I have listened again very carefully to this Khan's video. His exact words: " energy is generated by electrons going to lower energy state" From this link we got value for the generated energy. http://hypertextbook...mberIqbal.shtml " hydrolysis of a single ATP molecule, about 10-19 J." Trying to find out from where they got this value I ran to dead end. The book is not available for browsing on the net. Maybe you or somebody else has better resources available to find this information. The question also is: Is the sum of electron energies from orbital changes in question equal to this?

Thanks for your input. If it is not e-m radiation what is it then exactly? I have tried to find out what powers the muscle fibers to contract. From biochemistry the following book reference seemed to provide the answer. *Lehninger Principles of Biochemistry * Page 504 is dealing in great detail with phosphate bonds and goes to effect on muscle cells. However, it does not explain the exact nature of the chemical energy any better than anybody else as red lined below. "/In the contractile system of skeletal muscle cells, myosin and actine are specialized//*to transduce the chemical energy of ATP into reaction ........*//"/ Only reasonable conclusion seems to be that *nobody knows**what this (expletive deleted) energy is exactly.* The heat generated by mitochondria seem to be only 25% to 30%. The rest is something else. The following research report from 2004 deals with mitochondria and e-m radiation. This may lead to better understanding of our energy dilemma in the future. *Journal of Theoretical Biology 230 (2004) 261-270* P*ropagation of electromagnetic radiation in mitochondria?* "*Ultra-weak chemiluminescence appears as a general* *feature of all living organisms. It appears as a permanent* *weak light emission throughout the ultra-violet (UV),* *visible, and near-infrared (NIR) parts of the electromagnetic spectrum, which can be only detected by highly sensitive photo-multiplier-tubes...."*

I have read all the 'high-flying' posts on What is energy, exactly? thread. It has been interesting and educating. However, the question seems to remain elusive and unanswered. If you don't mind, I would like to bring this dilemma more down to earth. Years ago when feeling low on energy, I found all kinds of snake-oil peddlers pushing various energy boosters with caffeine mostly the main ingredient. Was wondering from where the energy really was coming from and found the role of mitochondria. Then Scientific American 2009 issue on page 86, on the left side, had an illustration showing how breaking the third phosphate bond of ATP releases a blob of energy. That was the AHAA moment for me. It soon fizzled to ahaa after finding the "What is energy, exactly?" thread on this forum. No better explanation for the blob of energy than "releasing the energy to power cellular activities". The following link gave the best explanation of ATP so far. Without defining the released energy better than referring to orbital energies of electrons and to quantum theory. Finally the following link provided something more concrete to work with. http://hypertextbook...mberIqbal.shtml Bray, Dennis. Cell Movements. New York: Garland, 1992: 6. "What is this power requirement in terms of ATP molecules, the principle currency of energy in the cell? Hydrolysis of one gram mole of ATP releases about 470 kJ of useful energy; hydrolysis of a single ATP molecule, about 10-19 J." When dividing this by Plank's constant h = 6.626x10-34Js we get a frequency of f=1.50*10^14Hz. Link below puts it in near infrared region. Certainly helps keep cells warm. But how does it also help muscle cells do mechanical work? That probably belongs more likely to biochemistry than this forum. Any member familiar with quantum theory might want to pitch in for a view from that direction. Thank you! http://www.lbl.gov/M...ec/EMSpec2.html
