Answer:
Vacuum
Explanation:
A vacuum is usually defined as a space in which there is an absence of matter. It can also be said that there is an extremely low amount of pressure due to which the particles present in it are not affected by any type of process that occurs in space. The value of pressure is lower than the value of normal atmospheric pressure.
For example, sound cannot travel in space because there is no medium such as water and air through which the sound waves can propagate.
A mutation in human ATPase 6 from leucine to
arginine at position 156 may allow the movements of protons across the
membrane, but not rotating of the ring of c subunits.
This possible mechanism affect the function of
ATP synthase because there would be an uncoupling of proton translocation and ATP
synthesis. ATP synthase would remain sensitive to F0 proton conduction
inhibitors
