The enzyme is found in bacterial plasma membrane, in thylakoid membrane (chloroplast ATP synthase) and in inner mitochondrial membrane. The main function of the enzyme is ATP production.
In this case, the terminal velocity increases to about 320 km/h (200 mph or 90 m/s), which is almost the terminal velocity of the peregrine falcon diving down on its prey.
10 hilariously insightful foreign words. Terminal velocity is the term for the speed an object reaches when the force of drag, or air resistance, pushing against it is equal to the force of gravity pulling it down. An object dropped from a height will initially accelerate because of gravity.
