Q How long did it take the molecules to come to equilibrium when the membrane was permeable to both water and peptides? How long did it take when the membrane was just permeable to water? Explain any differences. What was the effect of changing the temperature of the system on the movement of the molecules across the membrane? Why did changing the temperature affect that movement? Were you successful in establishing equilibrium for the mystery cell by changing the concentration of molecules outside of the cell? If you were unsuccessful, what other method did you use to establish equilibrium? What enzyme is best for the breakdown of starch into sugars? What were the best environmental conditions under which that occurred? Did changing the temperature affect all of the enzymes in the same manner? Why did one of the enzymes perform better under higher temperatures than the others? If humans cannot survive under such high temperatures, hypothesize where this enzyme might have come from on earth. Did changing the pH affect all of the enzymes in the same manner? Why did one of the enzymes perform better under different pH levels than the others? This enzyme is used by humans. Where in the human body might this enzyme be found? Explain why.
