Enzyme Function and Digestion Issues

The video tutorial explores Claire's metabolism issues, focusing on digestion and enzyme activity. It covers the process of digestion, enzyme functions, and the role of pH in enzyme activity. Through experiments comparing Claire's data with a healthy dog, the tutorial identifies potential causes for Claire's symptoms, such as enzyme mutations, incorrect pH levels, and low enzyme production. The video concludes with testing hypotheses to determine the root cause of Claire's digestion problems.

What is the primary role of enzymes in the digestion process?

• To transport nutrients through the bloodstream

• To break down food into smaller molecules

• To increase the acidity of the stomach

• To absorb nutrients directly

Which enzyme is responsible for breaking down proteins in the stomach?

• Protease

• Pepsin

• Amylase

• Lipase

In the small intestine, which enzyme is responsible for breaking down lipids?

• Protease

• Amylase

• Pepsin

• Lipase

What was the result of comparing enzyme activity in Claire's stomach to that of a healthy dog?

• Claire's enzymes did not function at all

• Both had similar enzyme activity

• Claire's enzymes were less active

• Claire's enzymes were more active

What was observed about the enzyme activity in Claire's small intestine compared to the healthy dog?

• Claire's enzymes were less active

• Claire's enzymes did not function at all

• Claire's enzymes were more active

• Both had similar enzyme activity

Which of the following is NOT a potential cause of Claire's digestive issues?

• High enzyme production

• Low enzyme production

• Incorrect pH levels

• Enzyme active site mutation

What was concluded about the possibility of enzyme active site mutation in Claire's case?

• It was confirmed as the cause

• It was not tested

• It was ruled out as a cause

• It was partially responsible

How does pH affect enzyme activity in the small intestine?

• Enzymes work best at any pH

• Enzymes work best within a specific pH range

• Enzymes are inactive at all pH levels

• pH has no effect on enzyme activity

What was the pH level of Claire's small intestine during the experiments?

• 8.5

• 7.0

• 6.5

• 9.1

What was the final conclusion about the cause of Claire's digestive issues?

• High enzyme production

• Low enzyme production

• Incorrect pH levels

• Enzyme active site mutation
