i might have been mistaken. the ph of the human body is 5.5 and algae can grow in 5.0. What if these kids had algae growing in thier skin?
So how did the algae get into thier bodies??
I hope your body does not have a pH of 5.5. The blood pH of your average person is approximately 7.4. In the lungs this values goes up to 7.6, due
to the basic exhalation of CO2 from the blood and haemoglobin out through your lungs. In the tissues, this value is even more acidic than blood at
about 7.2, due to the byproducts of cellular metabolism (i.e. lactic acid, etc.). A blood pH of 6.8 is severly acidotic, and will result in death if
not dealt with expeditiously. Hence the problem diabetics have with keto-acidosis. Bottomline, algae-if it does grow in a pH of 5.0 (severely
acidic)-i would not expect it to grow in the extremely more basic environment of blood and tissues. The difference in H+ concentration from pH 7.2 to
5.0 is approximately 160 times more acidic. Remember, pH is a logarithmic scale.
In terms of the algae parasitically growing within these children's bodies, I would have to say that I don't feel this is possible. In the long
history of the evolution of life, cells- from which we have descended- did at one time carry photosynthetic vacuoles of chlorophyll. However, this
was BEFORE homo sapiens came along. In fact, modern mitochondria, the powerplants of our cells, strangely resemble a prokaryotic organism acting as a
synergistic parasite within the host of the cell. It just so happens this relationship became energetically favorable for both the cell and the
mitochondrial-related ancestor. Yet, there was a reason WHY organisms outside the realm of plants gave up chloroplasts for glycogen and metabolic
glycolysis. In light of this, if human bodies did somehow take up chlorophyll in the form of algae chloroplasts, which would seem to give off a green
color, I suspect that the human body would attack these chloroplasts or algae derivatives just like it would any infection or virus.
