The "internal helix" inside the centriole lumen (Stubblefield, Brinkley, 1967) revisited, a cytosol vortex from the centriole as a turbine-pump

in #biology6 years ago (edited)

Powered by motor proteins that convert energy from ATP hydrolysis to mechanical force, the squeezing-together of the centriole, with 9 helical blades that are arranged similar to a turbine, pumps cytosol down the central axis. The flow of cytosol through the centriole takes the shape of a vortex, where the "vacuum string" in the center of the vortex can be observed in electron photographs. The vortex takes a spiralling path because of centrifugal forces from that each blade pushes at the cytosol at an angle, the pumping-of-cytosol mirrors the helical structure of the centriole 9-bladed turbine-pump.
