Mitochondrial decay
Encyclopedia
Mitochondrial decay is one major cause of aging, leading to the subsequent death in humans. The mitochondria are the power producing organelles found in every cell of every organ. Their primary function is to generate ATP
through various energy cycles that involve nutrients and vitamins. ATP is needed for every movement, thought and action we make. Yet very little ATP can be stored in the body. Under normal conditions the mitochondria generate free radicals during the ATP production process and as a result subject themselves to a lot of free radical damage. As we age, the mitochondria become less efficient, fewer in number and larger. Accordingly, ATP production declines, and this may eventually lead to cell death.
As organs cannot borrow energy from one another, the efficiency of each organ’s mitochondria is essential to its repair processes and functions. If an organ’s mitochondria fail, then so does that organ. Enhancement and protection of mitochondrial function and structure are therefore instrumental in preventing and slowing aging.
Mitochondrial decay is a progressive disruption of mitochondrial structural integrity and functional ability with advancing age. It can cause impairment in cellular energy production and hence a decline in normal function, particularly in organs with high energy consumption such as the brain and the heart. Mitochondrial decay can also lead to an increase in free radical production and thus render a cell more prone to commit suicide (programmed cell death or apoptosis
). Some of the age-related diseases, including cardiovascular and neurodegenerative disorders, have been found to involve mitochondrial dysfunction. The maintenance of a youthful mitochondrial functional ability and antioxidant capacity has become a trend in preventive health.

Adenosine triphosphate
Adenosine-5'-triphosphate is a multifunctional nucleoside triphosphate used in cells as a coenzyme. It is often called the "molecular unit of currency" of intracellular energy transfer. ATP transports chemical energy within cells for metabolism...

Apoptosis
Apoptosis is the process of programmed cell death that may occur in multicellular organisms. Biochemical events lead to characteristic cell changes and death. These changes include blebbing, cell shrinkage, nuclear fragmentation, chromatin condensation, and chromosomal DNA fragmentation...
