摘要
Experiments on steady-state 細菌l cultures have uncovered several quantitative regularities at the system level. These include, first, the exponential growth of cell size with time and the balanced growth of intracellular chemicals between cell birth and division, which are puzzling given the 非線性 and decentralized chemical dynamics in the cell. We model a cell as a set of chemical 族群s undergoing 非線性 mass action kinetics in a container whose volume is a linear function of the chemical 族群s. This turns out to be a special class of dynamical systems that generically has 吸引子s in which all 族群s grow exponentially with time at the same rate. This explains exponential balanced growth of 細菌l cells without invoking any regulatory mechanisms and suggests that this could be a robust property of protocell
