    highlight mine.

    Looked into the microtubule transport system yet?

    Hmm, I just assumed that it was another redox reaction like iron oxidation. AFAIK atomic oxygen is never present in that oxidation reaction; it proceeds via exchange of free electrons, H+ and OH- radicals.

    Is there anything you believe that microtubules do NOT do? That might be a shorter list.

    Not much. They are ubiquitous throughout the body. Trillions of them. And transport is what they do.

    What are the functions of microtubules
    There are 4 main functions of microtubules:

    Whenever you see the word "cyto-" , microtubules are involved.

    I'm rusty on this (haha) but I think it starts with O2 being adsorbed on the iron surface and dissociating into adsorbed (and thereby stabilised) O atoms, which then pick up electrons from the metal, though one could maybe regard the adsorbed molecule as having some of the characteristics of O2⁻.

    This type of stabilisation is not available in reactions with organic molecules. Oxidation reactions in organic chemistry, where there are no metal surfaces to help, generally use agents other than free oxygen, which are more specific in how they react. It is interesting that cytochrome oxidase in fact relies on an iron atom to bind the O2, much as haemoglobin does for O2 transport.

    (But anyway, as cytochrome oxidase has nothing to do with micro-sodding-tubules, I suppose this discussion is off-topic.

    I am not complaining. This side discussion is very interesting and informative.....

    (and may even be tangently related)

    One thing is clear; blood (oxygen carrier) contains microtubules. Most all electro-chemical information processes do involve microtubules.

    Balance of microtubule stiffness and cortical tension determines the size of blood cells with marginal band across species

    This does not directly address consciousness, but it does speak of the role microtubules play in cancer, i.e. uncontrolled cell-growth.

    Finally Objectivity by Someone , exchemist in this case . All I asked was a simple and legitimate question . Thats all .

    Tee hee. Asexperia invoked a Write4U ism.

    As long as time is identified as a measurement of duration, I am happy when my perspective is compatible with other approaches to the question. When different perspectives have Common Denominators, it usually tends to strengthen the truth of both perspectives......

    I'm not with you. Do any of these terms appear on your Write4U roulette wheel? Or is it just the overall portentous meaninglessness?

    So essentially is one dimension which is divided into two dimensions . Of which neither exists nor can , could exsit in Reality .

    In a Mathematical Universe, such naturally forming chronologies are not unexpected, IMO.

    We do not Live in a Universe in that's its very existence depends on mathematics , Alone . By itself . In and of its self .

    Mathematics can not create a Universe that is Real and Physical .

    Correction; The above generality was hasty and ill-considered. Below is an attempt to correct the generality.

    What I meant to identify is the role microtubules play in the cytoplasm of cells and the cytoskeleton in particular.
