drink deep, or taste not the Pierian spring:
there shallow draughts intoxicate the brain,
and drinking largely sobers us again.
Alexander PopeI've been following Angelo Grasso on Facebook because he posts a lot of biochemistry stuff. His schtick is to post some complicated pathway or structure then marvel at how complex it is and how it had to be designed. For a while I was commenting on his posts in order to show him why his interpretation was wrong or misleading but he just kept posting more examples gleaned from biochemistry textbooks.
This is a classic examples of someone who knows just enough to be dangerous. His latest post is about glycolysis and membrane-associated electron transport in animals. You can see it on the reasonandscience.heavenforum website: Glycolysis. Here's the bottom line ...
The critical role oxygen plays in providing cellular energy can be seen in the following equation. If one were to add oxygen to a glucose molecule (a simple sugar), the result would be carbon dioxide and water—with an overall yield of 36 adenosine triphosphate (ATP) molecules! Cells utilize ATP as the energy currency for most reactions in the cell that require energy.I'd like to think that everyone who has ever taken a biochemistry course at university could explain where Angelo Grasso is going wrong and why the chicken-and-egg problem isn't a problem. However, of the 1500 students in our introductory biochemistry courses, which cover glycolysis, I'm willing to bet that only a handful know the answer.
C6H12O6 + 6O2 + 6CO2 + 6H20
(with a typical energy yield of 36 ATP)
This cellular process is known as glycolysis. Most proponents of evolution believe this process started by fermentation. From this, allegedly more complex forms of respiration evolved that require catalyzation by a large number of complex enzymes. But that is where a major problem arises. In order to break down the six-carbon sugar of glucose enzymes are required. Each step within the chemical reaction of glycolysis is further catalyzed by specific enzymes, whose origin is still unexplainable by evolutionary assumptions. Enzymes are proteins that are made within the cell—but their production requires energy. Thus, cells require ATP to manufacture enzymes before glycolysis can even occur. (The old adage of “it takes money to make money” is applicable here—it takes energy to produce energy!) As such, evolutionists have an enormous chicken-egg problem. Which came first, glycolysis to make energy or energy from glycolysis needed to make enzymes? Without the enzymes, glycolysis could not occur to produce ATP. But without the ATP those enzymes could not be manufactured. This is strong evidence that the process of cellular respiration is not the product of evolution. As John Maina and John West observed: “Molecular oxygen is vital for generation of energy that in turn is fundamental to life” (2005, 85:838).
The other point that should not be missed is that glucose and other sugars are only present within living things in nature. This would require plant material or other life forms in existence as a food source. So how does this requirement affect the evolutionary timeline? Why would organisms evolve cellular respiration if glucose or other sugars were not available? This necessity puts restrictions on evolution and the alleged evolutionary appearance of plants.
Finally, we must ask the question of how the first living cells survived if they were still evolving a mechanism to produce and store energy in the form of ATP? If a cell is unable to make proteins, get rid of waste, or successfully divide, then how long would it survive? The obvious answer is that cells have always possessed the ability to manufacture and store energy. Our bodies were designed in such a way that complex cascades of chemical reactions occur continuously in cells throughout the body without any conscious effort on our part. We know today that the absence of one of the steps involved in these complex cascades can have dire effects on cellular growth. The only logical explanation is that a Master Architect laid out these complex steps, and we are slowly uncovering the handiwork of that Designer.
I'm not going to tell you the answer. Instead, I'd like you to answer the poll question in the left-hand margin. You can answer after you've read the comments but try and be truthful. Nobody (including me) will ever know whether you knew the right answer or not because the internet is very secure.
