Polymerization of tubulin
WebThermodynamics takes the whole system into consideration for calculating entropy or free energy. When free tubulin is in the cytosol, it interacts with so many H 2 _2 2 O molecules that are in association with it. Even though tubulin becomes microtubule by polymerization leading to a decrease in entropy, the resulting release of H 2 _2 2 O molecules into the … WebOct 18, 2024 · In addition to tubulin polymerization inhibition, 19h caused cell cycle arrest in MCF-7 cells at the G2/M phase and induced apoptosis.
