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.
Answer:
11. Why do scientists assume that experimental results can be reproduced? A key assumption in science is that nature behaves in a consistent manner.
12. What did Anton van Leeuwenhoek discover? He discovered a world of tiny moving objects, which he called "animalcules," in rainwater, pond water, and dust.
13. What did John Needham conclude from his test of Redi’s findings? He concluded that the little animals in a bottle of broth could only have come from the juice of the broth.
14. What did Spallanzani do to improve upon Redi’s and Needham’s work? He boiled two containers of broth, assuming that the boiling would kill any microorganisms that were present.
15. How did Pasteur settle the spontaneous generation argument? He designed a special flask to show that as long as broth was protected from microorganisms, it remained free of living things.
Explanation:
I don’t have a complete answer but I’ll help u some. Building dams and rerouting rivers are two examples of ways humans directly impact water in watersheds. Humans also use water as a resource, drawing from watersheds for our drinking water. This does not have to be a negative impact, as water usage can be monitored so that it is sustainable. Hope this helped. ;)
Answer:
Statements 1, 2 and 4 are correct:
"Hormones can be peptides, steroids, or amino acid derivatives."
"Hormones can stimulate the synthesis of target proteins through the activation of specific genes."
"Hormones can increase the cellular uptake of metabolites."
Explanation:
Hormones are basically proteins that are released under particular conditions to bring about a certain response in the body. They can activate genes and even change how cells respond to metabolites, for instance, insulin and glucagon are two hormones that regulate the level of sugar in the blood. Another example is the hormone adrenaline, which is released in the 'flight-or-fight' response to prepare the body in taking action.
