QUESTION 9
How did this experiment with Benedict's solution demonstrate the digestion of starch by amylase? In other words, how did you know the starch was digested?
| We compared control samples with samples that had been treated with amylase and measured the pH using a pH indicator. When the solution becomes orange or red, it indicates that the starch has been digested. | ||
| We compared control samples with samples that had been treated with amylase and used a Benetict's test for Reducing Sugar. When Benedict's turns orange/red it indicates that starch has been digested. | ||
| We compared control samples the sample to been treated with amylase and observed which had become liquefied. The solution becomes liquefied, it indicates that the starches have been digested. | ||
| Compare control samples with samples that had been treated with amylase. Benedict's turns light blue it indicates that starch has been digested. |
QUESTION 10
What happens to saliavry amylase when it arrives with the bolus in the stomach? Because of this, what happens to charbohydrate digestion? (Hint: Look up the optimum pH for amylase and what is the pH of the gastric juices)
| When the bolus hit the stomach, the amylase enyzmes continue to function and starch digestion continues. | ||
| When the bolus hit the stomach, the amylase enyzmes denature and cease to function and starch digestion stops. | ||
| When the bolus hit the stomach, the amylase enyzmes denature and cease to function. However, starch digestion continues because pepsin continues the digestion of starch. |

Digestion is the
| conversion of glycogen to glucose. |
| absorption of nutrients suspended in water. |
| churning of food in the stomach and intestine. |
| breakdown of food into molecules small enough for the body to absorb. |
