QUIZ 3 Flashcards
if you were to look at the three test tubes involved at the enzyme concentration experiment after 24 hrs, how would the colors of each compare
Similar color because ENZYME will RECYCLE and get to similar results.
Both High and Low temperatures reduced the amount of color (product) produced. However, the cause of the reduction is different in two cases. Explain what the differences are.
- At a High temperature they denature.
- At a Low temperature they Slow down their reaction rate.
Why does increasing the amount of substrate increase the amount of color produced in test tubes?
Enzyme activity increases the substrate concentration. And so will more color will be produced ad the activity increases.
At what PH was the enzyme more effective?
PH 7
At what PHs did the enzyme work but not as effectively?
PH 5
Explain why changing the PH altered the effectiveness of the enzyme.
Enzymes are being moved out of its optimal range/ denature it.
In a perfectly tied unbroken bag, should we see evidence of sugar molecules passing through the “membrane”? Qualify your answers in terms of how selective permeability operates.
No, because the molecule id too big.
There would be evidence of water passing through membrane, this is because of Osmosis. The tubing allows water in but not the sugar.
From your graph of the influence of temperature on the rate of osmosis, what can you conclude about the effects of temperature on the rate of Osmosis? Hint: How are temperature and molecular motion related.
As Temperature increases the rate of Osmosis increases.
How do differences of concentration affect the rate of osmosis? why is there a difference?
As you increase the concentration the rate of osmosis increases. The Lower the concentration of a solute the faster the rate of osmosis.
