It is a polar molecule because it has a partial positive and negative charge from hydrogen and oxygen respectively.

Answer: has a partial positive and negative charges at each end

Explanation:-

Electronegativity is defined as the property of an element to attract a shared pair of electron towards itself.

A polar covalent bond is defined as the bond which is formed when there is a difference of electronegativities between the atoms. It is also defined as the bond which is formed due to the unequal sharing of electrons between the atoms.

Water is formed by the sharing of electrons between hydrogen and oxygen where the shared pair lies more towards oxygen due to its high electronegativity and thus bears a partial negative charge.Whereas hydrogen being less electronegative bears a partial positive charge.

Mitochondrial inner membrane fragments that contain ATP synthase can be isolated in the lab. Under appropriate conditions, these
Neporo4naja [7]

Answer:

The optimum pH of ATP synthase is 6.4 therefore maximum activity  will  occur at pH7  by the vesicle, however because the concentration of the  three , is relatively the same , and exhibited  equal effects  on  the pH,  catalysis  by the vesicle will  not take place BECAUSE NO  HYDROGEN ION IS AVAILABLE  to supply the energy

Generally the synthase activity decreases with drops in pH. The lower pH  of 6.5 from the  set point value , will affect catalysis.

The low pH     lead to  increase in  concentration of base in  the buffer solution. Therefore more H +  are produced .for the synthesis of ATP. The  vesicle catalyzed ATP production.  But the increase in hydrogen ion concentration with time  affect the 3 dimensional structure of the ATPase synthase enzyme in the vesicle and increases the inhibitory effect of ADP therefore  the  vesicle stops the catalysis.
