dbosman; thanks for the info the animation about the Krebs cycle was great very informative thank you!
The product does little for plants however(they use the Kreb's as well, like us, to produce energy from the sugars they fix). We are interested in the Calvin cycle. Growth etc, fixing of Carbon, production of sugars(like glucose).
Krebs is not going to be improved upon much by adding concoctions for enhanced plant growth.
think about it, what is the Krebs cycle using ? Sugar to burn for energy.......enhancing that rate of production is going to be tough without some cost and trade offs, and the plant will self regulate it anyway at the end of the day.
You could add table sugar and make this same claim, or any number of the intermediates, but the rate limiting step will still be something else downstream unless the entire cycle is enhanced at each step.
So adding more mitrochondria per cells, higher rate of metabolism etc would increase the rate of growth(the factor that plants are concerned with). Growth is much more about fixing Carbon than burning it, plant's metabolic rates are much slower than say critters that move around and do not fix carbon. So this will not improve the rates of growth of plants, only help them burn there fuel faster really.
I could suggest that this product could deplete the Carbon supply in plants and thus increase the CO2 demand, making it harder to keep up with nutrients/CO2 etc.
Sounds fishy to me and more a marketing ploy vs any real useful thing aquarist could use, on the other hand, like any high grade snake oil, it will not hurt the plants, fish etc either
