If we set up an experimental design to explore the full digestion of starch to glucose, we would need to include which enzymes?
A) pepsin and hydrochloric acid
B) amylase and maltase
C) trypsin and maltase
D) pepsin and lipase
E) trypsin and lipase
Amylase
An enzyme that helps in breaking down carbohydrates into simpler sugars, mainly found in saliva and pancreatic fluid.
Maltase
Enzyme produced in the small intestine that breaks down maltose to two glucose molecules.
Pepsin
An enzyme produced in the stomach that initiates the digestion of proteins by breaking them down into smaller peptides.

Final Answer :
B
Explanation :
Starch is digested by the enzyme amylase, which breaks it down into maltose. Maltose is then further broken down into glucose by the enzyme maltase. Therefore, including both amylase and maltase in the experimental design would allow for the full digestion of starch to glucose. Choices A, C, D, and E include enzymes that are not involved in the digestion of starch.
