Photosynthesis Relies on Quantum Coherence

It is no secret that nature’s process of photosynthesis—which harnesses the energy in sunlight—is astonishingly efficient. And researchers have known for years that quantum mechanisms play a role in the protein antenna farms deployed in these marvelous molecular machines. Now new research, based on a experimental technique that tracks these proteins at the femtosecond level (there are a million billion femtoseconds in a second), elucidates some of these quantum mechanisms and, as usual, the results are surprising.  Read more

  1. Related notes: At the 21:00 minute mark of the following video, Dr Suarez explains why photosynthesis needs a ‘non-local’, beyond space and time, cause to explain its effect:

    The Elaborate Nanoscale Machine Called Photosynthesis: No Vestige of a Beginning – Cornelius Hunter – July 2012
    Excerpt: “The ability to do photosynthesis is widely distributed throughout the bacterial domain in six different phyla, with no apparent pattern of evolution. Photosynthetic phyla include the cyanobacteria, proteobacteria (purple bacteria), green sulfur bacteria (GSB), firmicutes (heliobacteria), filamentous anoxygenic phototrophs (FAPs, also often called the green nonsulfur bacteria), and acidobacteria (Raymond, 2008).”

    “Despite its complexity, C4 photosynthesis is one of the best examples of ‘convergent evolution’, having evolved more than 50 times in at least 18 plant families (Sage 2004; Conway Morris 2006).”

    Evolutionist Has Another Honest Moment as “Thorny Questions Remain” – Cornelius Hunter – July 2012
    Excerpt: It’s a chicken and egg question. Scientists are in disagreement over what came first — replication, or metabolism. But there is a third part to the equation — and that is energy. … You need enzymes to make ATP and you need ATP to make enzymes. The question is: where did energy come from before either of these two things existed?

    At the 6:00 minute mark of the following video, Chris Ashcraft, PhD – molecular biology, gives us an overview of the Citric Acid Cycle, which is, after the 10 step Glycolysis Pathway, also involved in ATP production:

    ATP: The Perfect Energy Currency for the Cell – Jerry Bergman, Ph.D.
    Excerpt: In manufacturing terms, the ATP (Synthase) molecule is a machine with a level of organization on the order of a research microscope or a standard television (Darnell, Lodish, and Baltimore, 1996).

    ATP Synthase, an Energy-Generating Rotary Motor Engine – Jonathan M. May 15, 2013
    Excerpt: ATP synthase has been described as “a splendid molecular machine,” and “one of the most beautiful” of “all enzymes” .,, “bona fide rotary dynamo machine”,,,
    If such a unique and brilliantly engineered nanomachine bears such a strong resemblance to the engineering of manmade hydroelectric generators, and yet so impressively outperforms the best human technology in terms of speed and efficiency, one is led unsurprisingly to the conclusion that such a machine itself is best explained by intelligent design.

  3. Visible light is also incredibly fine-tuned for life to exist. Though visible light is only a tiny fraction of the total electromagnetic spectrum coming from the sun, it happens to be the “most permitted” portion of the sun’s spectrum allowed to filter through the our atmosphere. All the other bands of electromagnetic radiation, directly surrounding visible light, happen to be harmful to organic molecules, and are almost completely absorbed by the atmosphere. The tiny amount of harmful UV radiation, which is not visible light, allowed to filter through the atmosphere is needed to keep various populations of single cell bacteria from over-populating the world (Ross; reasons.org). The size of light’s wavelengths and the constraints on the size allowable for the protein molecules of organic life, also seem to be tailor-made for each other. This “tailor-made fit” allows photosynthesis, the miracle of sight, and many other things that are necessary for human life. These specific frequencies of light (that enable plants to manufacture food and astronomers to observe the cosmos) represent less than 1 trillionth of a trillionth (10^-24) of the universe’s entire range of electromagnetic emissions. Like water, visible light also appears to be of optimal biological utility (Denton; Nature’s Destiny).
