Newsweek article “The Secrets of the Human Cell” explains:
“Each of those 100 trillion cells functions like a walled city. Power plants generate the cell’s energy.
Factories produce proteins, vital units of chemical commerce.
Complex transportation systems guide specific chemicals from point to point within the cell and beyond.
Sentries at the barricades control the export and import markets, and monitor the outside world for signs of danger.
Disciplined biological armies stand ready to grapple with invaders.
A centralized genetic government maintains order. Cells do their work silently, processing prodigious volumes of information with tremendous speed.”
Carl Sagan wrote,
“A living cell is a marvel of detailed and complex architecture. Seen through a microscope there is an appearance of almost frantic activity.
On a deeper level it is known that molecules are being synthesized at an enormous rate. Almost any enzyme catalyzes the synthesis of more than 100 other molecules per second.
The information content of a simple cell has been estimated as around 1012 bits, comparable to about a hundred million pages of the Encyclopedia Britannica.”
