What is the working mechanism of ATP synthase? Functionally, ATP synthase is tripartite, consisting of (1) a motor in the membrane that converts electrochemical ion gradient energy into subunit rotation, (2) a rotating transmission device, the ‘rotor stalk’, which transmits the energy over a distance of greater than 100 Å to the catalytic sites, and […]
Does WD 40 remove oil stains from clothes?
Does WD 40 remove oil stains from clothes? WD-40 is a petroleum-based lubricant that can cause stains on clothes. But it also can help to remove stains. The solvents in WD-40 help to break down oil—especially old oily stains—loosening the oil molecules from fabric fibers. Simply spray the stain with a bit of WD-40 from […]

What is the similarities between speed and velocity? Speed and velocity both represent a way to measure the change in position of an object relative to time. In fact, for a straight line motion, the speed and velocity of an object are the same (since distance and displacement will be the same). Speed and velocity […]
