Sol-gel theory

WebAug 5, 2013 · Cytoplasmic sol–gel conversion is important in many cellular processes, e.g., the elastic response of the gel-like body of the cell is essential to stop bleb growth . When the elastic structure inside a cell cannot withstand pressure from the active cortex, the entire cytoplasm is spontaneously carried into a bleb ( Figure S2 and Movie S2 ). WebMar 11, 2024 · One of the major assumptions of the dimer-gel theory is a mean-field approximation. Mean-field theory ignores correlations in binding between stickers in the same chain, and therefore has been applied to long chains in the weak binding regime (such that not every sticker is bound) (Prusty et al., 2024; Choi et al., 2024b).

WebWhat is sol-gel theory in amoeba? Sol-gel theory Locomotion of an amoeba is thought to occur due to the sol-gel conversion of the protoplasm within its cell. ‘Sol-gel conversion describes the contraction and relaxation events which are enforced by osmotic pressure and other ionic charges. 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.
