Question
Grade 11 learners want to investigate which enzyme is responsible for chemical digestion of starch into glucose in humans. They are provided with two different enzymes (carbohydrase and proteases ),starch powder,warm water at about 37 and basic glass apperatus and chemicals to test for glucose.
Formulate a hypothesis for this investigation?
Identity the following variables
(a) independent variable
(b)dependent variable
(c) fixed or controlled variable
Why should the water be at about 37?

1.1 Carbohydrase is responsible for starch into glucose
1.2 a starch powder
b enzymes
c water temperature
1.3 because enzymes in humans function best at 37 ℃
