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.
Explanation:
Solar UV radiation. Australia experiences some of the highest levels of UV radiation in the world because we are close to the equator and have many clear, blue-sky days. The Earth's orbit also brings countries in the southern hemisphere (Australia included) closer to the sun in the summertime than countries in the northern hemisphere during summer.
Chemical, digestion mechanical, thinking
The answer would be D. Biomass I hope this helped ^^
