cellular respiration

This site breaks down the process of cellular respiration. It is written in a way that a person with some understanding of biology will be able to learn the process. I appreciated it because the chapter in my textbook was a bit convoluted.

Exciting Info about Reproduction

Sexual reproduction provides genetic diversity through recombination. This genetic diversity may serve the population well as the environment changes or as the population expands into new environments. The adaptability resulting from genetic diversity is the major advantage of sexual reproduction over asexual reproduction, although sexual reproduction can also break up well-adapted combinations of alleles through the same process of recombination.
Asexual reproduction is the only way of raising plants such as navel oranges, all of which have been reproduced from a single tree found in on a plantation on the Brazilian coast in the early 19th century.

Alkalinity and acidosis of the blood

In humans, a normal pH of all tissues and fluids of the body is slightly alkaline. The most critical pH is in the blood. All other organs and fluids fluctuate in their range in order to keep the blood at between 4.35 and 7.45 pH

If the blood becomes too acidic then it robs some of the alkaline forming elements from the enzymes in the small intestine to maintain homeostasis. The small intestine then becomes to acidic to digest foods properly. The pancreas, gallbladder and liver must then work harder to make up for this deficiency in order to metabolize foods properly. This negatively impacts metabolic enzyme production, resulting in lowered immune function, fatigue, hormonal imbalances and absorption and digestive problems.

The bones begin to leach calcium when pH is too acidic, resulting in bone density problems.

Insulin levels increase and fat is stored rather than being metabolized.

Electrolyte imbalances occur that can negatively impact the nerve, heart and muscle cells.

A hyperalkaline state can cause muscle cramps and weakness.
