Digestive System Functions and Enzymes

This video from MooMooMath and Science explores the movement of food through the digestive system and the role of enzymes in digestion. Enzymes speed up chemical reactions by reducing the energy needed to start them. The video covers the digestive process starting in the mouth with enzymes like lipase and amylase, continuing in the stomach with pepsin, and further digestion in the small intestine with pancreatic enzymes and lactase. The importance of enzymes in breaking down proteins, carbohydrates, and lipids is highlighted, along with a brief mention of lactose intolerance.

What is one way enzymes assist in digestion?

• By slowing down chemical reactions

• By eliminating the need for chemical reactions

• By reducing the energy needed to start reactions

• By increasing the energy needed for reactions

Which enzyme is responsible for breaking down lipids in the mouth?

• Lipase

• Lactase

• Amylase

• Pepsin

Where does protein digestion begin?

• Esophagus

• Small intestine

• Mouth

• Stomach

What is the primary enzyme in the stomach?

• Lipase

• Amylase

• Lactase

• Pepsin

What does pancreatic juice break down?

• Only carbohydrates

• Proteins, glycogen, and starch

• Only lipids

• Only proteins

Where is the pancreatic duct located?

• Large intestine

• Mouth

• Stomach

• Duodenum

What enzyme breaks down lactose in the small intestine?

• Amylase

• Lipase

• Pepsin

What happens if you are lactose intolerant?

• You have an excess of lactase

• You lack or have reduced lactase

• You have an excess of lipase

• You lack or have reduced amylase
