The all-or-nothing theory, or law, does not just come into play in regards to cells. It can be used in reference to electrical laws, political ideologies, and many more areas of life in general. Its basic principle is that there is no middle ground. In politics the all-or-nothing law may be applied to issues such as abortion.
In cellular theory it is the same thing. Our cells are often changing as our bodies tell them to. How these cells change are by bonding with proteins, or certain chemicals. The all-or-nothing law protects our cells from having problems, not that they don’t anyway. For example say our body decides to kill a cell, it’s just it’s time it happens a million times a day. The cell receives orders through various means to break down and re-distribute its components to other areas in the body. But say the orders were unclear; say there weren’t enough proteins to get the message across to all areas of the cell. Instead of beginning the process of breaking down and quitting half way, the cell simply ignores the command and waits for more information. The cell will not half die, it’s all or nothing.
The theory is wide spread and can be seen in many areas.
