Enzyme Action: Trypsin

The video explores the role of enzymes, focusing on trypsin, an enzyme in the digestive system. An experiment is conducted to observe trypsin's effectiveness at different temperatures: 20°C, 37°C, and 60°C. At 20°C, trypsin partially digests gelatin, while at 37°C, it is more effective due to increased molecular energy. At 60°C, trypsin becomes denatured and ineffective. The video explains enzyme-substrate interactions, highlighting gelatin as the substrate. It also discusses enzyme denaturation and applications in products like biological detergents.

What is the primary role of trypsin in the digestive system?

• To digest proteins

• To absorb nutrients

• To break down carbohydrates

• To emulsify fats

What materials are needed for the trypsin experiment?

• Test tubes, 10% trypsin solution, oven

• Petri dishes, 1% trypsin solution, refrigerator

• Glass slides, 5% trypsin solution, incubator

• Photographic film, 2% trypsin solution, water bath

At what temperature does trypsin work most effectively?

• 80°C

• 20°C

• 37°C

• 60°C

What happens to trypsin at temperatures above 60°C?

• It becomes more active

• It denatures and loses function

• It changes color

• It becomes a solid

What is the substrate used in the trypsin experiment?

• Lactose

• Starch

• Gelatin

• Cellulose

Why is the solution in the boiling tube at 37°C darker than the one at room temperature?

• The trypsin has evaporated

• The trypsin has digested more gelatin

• The gelatin has solidified

• The trypsin has changed color

How do enzymes in biological detergents help in cleaning clothes?

• By changing the color of clothes

• By adding fragrance

• By making clothes softer

• By breaking down and removing stains
