| Abstract: | The probability of escape for a mimic Brownian movement particle from a one dimensional potential well,which is drived by the molecule motor, is presented by Fokker Planck equation. The hydrolysis probability of ATP molecule and the reaction probability of the motor protein molecule are showed. The statistical formulas about the molecule motors number and ATP molecules number which are joined with the membrance of a particle in the living cell are given. |
