I think the answer you want is lysosomes
Answer:
The modified hemoglobin with free imidazole cannot be expected to show cooperativity in oxygen binding. The movement of iron ion takes place up in the plane of heme when binding of one subunit of hemoglobin takes place with oxygen. One of the iron's and oxygen's axial ligands comprise the proximal histidine's imidazole ring.
With the movement of iron into the hemoglobin ring, the pulling of proximal histidine takes place along with it. Therefore, when binding of oxygen takes place with one subunit, a modification also takes place in the intersubunit associations, this also comprises displacement of the alpha helix. This phenomenon plays an essential role in modifying the hemoglobin's tensed state to the relaxed state. The withdrawal or mutation of the imidazole ring from the histidine residue does not further permit the cooperative binding as it is not associated physically with the alpha-helix.
These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if an error is made as DNA copies itself during cell division. Acquired mutations in somatic cells (cells other than sperm and egg cells) cannot be passed to the next generation.

When cells do not
respond to the signals that normally regulate cell division, cancer results. Cancer cells altered cell division in the
presence of signals that normally inhibit cell growth, with this; they no
longer require special signals to induce cell growth and division. The consequence
of the abnormalities of these cells could lead to mutations in protein-encoding
genes that regulate cell division.
<span>Moreover, they
also inhibit the growth of nearby cells that allow the cancer cells to spread
and invade other tissues. The uncontrollable division form masses of cells
called tumors that can impaired nearby tissues. If these cells stay in their
original site, they are considered benign, if they become invasive, they are
considered malignant which means that cancer cells metastasize, sending tumor
cells to distant locations in the body where new tumors may form.</span>
Already a few months prior after being buried, the body is already decaying. The body builds up with gas and has nowhere to go so the body becomes bloated thus attracting insects that break down the body and eat away as it progresses through the decaying process. The body goes through 5 stages of decay and thats autolysis and putrefaction. Autolysis, the body's enzymes begin to go into a meltdown and its sped up by extreme heat and slowed by extreme cold. Putrefaction is the bacteria that escapes from the body's intestinal tract and actually begins the process of literally melting the body down. Black purification is when the skin turns black and the corpse collapses and the gasses escapes. Fermentation is when the strong odors develop and there will be surface mold but the body has begun to dry out. Dry decay is when the cadaver has mostly dried out and the decaying process has slowed considerably. This when it starts taking longer but all the nasty stuff is over. So after twelve years and all that happens within the first years of being dead with or without a coffin at that. But in the end the body will be fully decomposed in 8-12 years and all that is left are the bones.
