Is photosynthesis a form of cold fusion?

    Well Dr. Kaku?

    I'm not Dr. Kaku, but the answer is no, it isn't.

    Photosynthesis accomplishes its goals by moving electrons around, breaking up molecules, and reassembling the pieces into other molecules. All of that is chemistry and has nothing at all to do with nuclear fusion.

    I see. In what way exactly?

    Scientifically speaking. For instance does the photon impact the atom,
    and bump the electron up to a higher level of energy, a higher shell allowing a covalent bond to form in a complex molecule or what exactly?

    Your explanation does not sound very scientific.

    How does the carbon taken from the atmosphere, become green plant life?

    What happens to an element in fusion?

    For photosynthesis, see here.

    In fusion, elements are turned into heavier elements (atomic weight). For example in the Sun's fusion, four protons (Hydrogen nuclei) are fused into one Helium nucleus. This does not happen in phtosynthesis, the elements retain their identity.

    There is a complex of chlorophyll molecules dubbed "photosystem II." When an electron is excited in any of them, it returns to its normal valence shell and excites an adjacent electron until a specific chlorophyll molecule called P680 is excited. It completely loses its electron, which moves to a primary electron acceptor. When P680 loses its electron, it becomes an oxidizing agent and splits a water molecule into two hydrogen ions and an oxygen atom. When this happens twice, you get four hydrogen ions and an oxygen molecule. The electron, meanwhile, moves down an electron tranport chain to another complex of chlorophyll molecules called photosystem I, where it is accepted by P700, which had also had an electron removed by a photon. That electron moves to another primary acceptor and down a separate electron transport chain to an NADP+ reductase molecule, which reduces NADP+ to NADPH plus a hyrogen ion (using the hydrogen ions previously split from the water molecule). ATP is made during the steps of the electron transport chains, NADPH moves to the Calvin Cycle, where carbon dioxide is split and reassembled into glyceraldehyde-3-phosphate, which can be made into glucose and other carbohydrates. The oxygen molecules are released as waste products.

    Thankyou. It sounds as if you are ready to begin doing it better.

    :wink:

    Heh, I probably would have said, fusion requires the nucleus.
    Photosynthesis simply involves a chemical reaction.

    My point is simply this, that for some strange reason, people in physics,
    often appear to think that there are separate elements and constritutent
    parts for an atom in physics and an atom in chemistry when of course you are
    dealing with the same objects.

    Where we should be in physics, is the understanding that matter has a wave property, and a frequency that is measureable and consistent in its normal natural at rest state, and that there a world of scientific advances to be
    made in medicine and longevity, if they could just stop looking at atomic
    processes entirely as a zoo of particles, and begin to see that, if you effect
    the matter wave to the point where you can normalize it, then you can affect
    the element, effect the atom, affect the cell, affect the body.

    There is probably a machine lying in wait in our future which will be able to
    bring the atoms of a body, into a normal proper state, and thereby cure
    desease, and repair cell structure.

    When you combine chemicals, you are merely affecting the state of the
    atoms. Affecting their covalent bond and their ability to form other
    substances.

    Laser treatment in for instance a tennis elbow injury, is a good example of
    how waves help to repair tissue.


    And it is my belief as well, that if you were more exact with your methods,
    and less quantum smearing was promoted or acepted then you would not
    need vast amounts of energy to affect processes.

    Where the problem lies in physics, and where chemistry is making better advances than physics, is the recognition, that exactly measured quantities
    are not only possible but the key to well managed processes and good science.

    One once of pure gold, has an exact number of atoms.

    The element gold, has an exact unchanging frequency.

    As do all the other elements.

    Chemistry knows this. Physics does not appear to believe that such things
    are important, when of course, that is the key to understanding the macro
    world.

    Rick Sobie,

    I strongly suggest you attempt to learn more physics and chemistry before making such grandiose and, well, silly claims about them.
