Lab 9: Digestive System Physiology Flashcards
What is starch?
Starch is a huge polysaccharide made of monosaccharides (glucose). A common starch is amylose
What was the experiment testing and what was the question?
The digestive ability of amylase to break amylose to reducing sugars.
What is the ideal pH for amylase to break down starch into smaller sugars?
What can affect the function of enzymes?
pH and temperature
What was your hypothesis and prediction, where they supported?
A pH of 1 will be the best pH to digest starch into smaller sugars therefore the starch solution will turn red fastest in the pH of 1 and the slope would be greater. They were not supported
What were the results of the starch experiment?
The color (designating the amount of reducing sugars: blue: 0, green: 1, orange: 2, red:3) of the pH 7 slowly increased from 1.1 to 2.6 while the color of the pH 1 increased from 0.4 to 0.9.
