Note- second primary source (Peskin et al., p. 317 fig.1) give value of ~7.8pN according to equation 4 (p. 318): fo=-(kBT/d)×ln(ß/a) where fo is the force, kBT is the product of the Boltzmann constant, kB, and the temperature, the
size of a monomer is indicated by d, and ß and a are the rate constants for actin polymerization. |
