Enzyme Functions and Applications

What is the role of chymosin in cheesemaking?

• To add flavor to the cheese.

• To prevent milk from spoiling.

• To curdle milk by clipping casein.

• To extract enzymes from animal stomachs.

What is the primary function of an enzyme?

• To slow down chemical reactions.

• To act as a blueprint for life.

• To speed up chemical reactions.

• To provide structural support to cells.

How are enzymes produced in microbes?

• By feeding microbes specific nutrients.

• By inserting DNA that codes for the enzyme into the microbe.

• By exposing microbes to extreme temperatures.

• By manually assembling amino acids within the microbe.

What is a significant environmental benefit of using engineered enzymes in laundry detergent?

• They make clothes last longer.

• They reduce the need for water heating, saving energy and reducing CO2 emissions.

• They eliminate the need for water in laundry.

• They make laundry detergent biodegradable.

Are you enjoying the video lesson?

• Yes

• No

What is a key benefit of evolving enzymes through repeated cycles?

• To make them less stable in various conditions.

• To reduce their overall size and complexity.

• To create new enzymes with desired functionalities.

• To increase their natural abundance in the environment.

Why was milk used in the enzyme demonstration?

• It is a common household liquid that is easy to obtain.

• It contains a high concentration of proteins, making enzyme action visible.

• It changes color dramatically when exposed to enzymes.

• It represents the typical composition of laundry stains.

Which of the following is a current approach in enzyme design?

• Exclusively relying on naturally occurring enzymes without modification.

• Designing enzymes from scratch using machine learning.

• Limiting enzyme applications to traditional industries only.

• Removing all amino acids from enzymes to simplify their structure.

How can enzymes contribute to environmental solutions?

• By increasing the production of non-biodegradable plastics.

• By enhancing the release of greenhouse gases into the atmosphere.

• By degrading plastics and capturing greenhouse gases.

• By promoting the use of petroleum-derived products.
