Sol-gel theory

The protoplasm of an amoeba is made up of an outer layer termed the ectoplasm which surrounds an inner portion called the endoplasm. The ectoplasm consists of a gelatinous semisolid called plasma gel whereas the endoplasm is made up of a less viscous fluid called plasma sol. The ectoplasm owes its highly viscous state, in part, to the cross-linking actomyosin complex. Locomotion of an amoeba is thought to occur due to the sol-gel conversion of the protoplasm wit… WebAug 26, 2024 · Kundu CK, Song L, Hu Y.
