proteins that help break down large molecules into smaller molecules
  • enzymes
  • saliva
  • bili
  • gastric juice
TRUE or FALSE:Enzymes speed up, or catalyze the rate of chemical reactions.
  • FALSE
  • TRUE
TRUE OR FALSE:Enzymes change the chemical reaction
  • TRUE, but not entirely
  • FALSE, they just speed it up
  • FALSE, they have no role in chemical reactions
The digestive system produces enzymes that are specialized to help break down each type of
  • food molecule
  • chemical reaction
  • bolus
  • stool
What are the 2 parts that make up the digestive system?
  • the digestive tract and the blood vessels
  • the digestive tract and other organs (such as tongue and liver)
  • All of the organs of the human body and the mouth
  • the mouth and the stomach
___________ are enzymes that help break down carbohydrates.
  • Amylase
  • Papain
  • Lipase
  • Pepsin
___________ are enzymes that help break down fats.
  • Lipase
  • Amylase
  • Papain
  • Pepsin
A muscular tube that connects the mouth and the stomach.
