WebMar 11, 2024 · Treadmilling occurs in actin filaments and microtubules. Dynamic instability allows the cells to reorganize the cytoskeleton rapidly when needed. Treadmilling … WebSep 12, 2024 · ATP hydrolysis on actin is the key reaction that allows filament treadmilling. It regulates barbed-end dynamics and length fluctuations at steady state and specifies the functional interaction of actin with essential regulatory proteins such as profilin and ADF/cofilin. Which components of the cytoskeleton undergo treadmilling?
WebSolution: The correct answer is C . Figure 1 shows that at free actin concentrations greater than 1µM, actin is added to the + end of a microfilament. At concentrations lower than 1µM, the + end loses actin subunits. The – end of the microfilament does not begin to add actin until the free actin concentration is greater than 5.5µM. WebAs new pieces of actin are moved to the front of the line, the cell membrane is forced to move forward. The result is the cell creeping along. Actin treadmilling is a convenient …
