Substrate

The video tutorial explains the concept of 'substrate' across different scientific fields. In material science, a substrate is the surface on which a coating is applied. In biochemistry, it refers to the substance on which an enzyme acts. In biological science, a substrate is the material found at the bottom of a body of water, such as silt and stones on a riverbed.

In material science, what is the primary role of a substrate?

• To act as a catalyst

• To serve as a surface for coating

• To provide nutrients

• To absorb moisture

What does a substrate refer to in biochemistry?

• A substance that an enzyme acts upon

• A chemical inhibitor

• A surface for painting

• A type of protein

In biological science, what is a substrate?

• A type of plant

• A type of microorganism

• A layer of atmosphere

• Material at the bottom of a body of water

Which of the following is an example of a substrate in a riverbed?

• Fish

• Water

• Algae

• Silt and stones

How does the concept of substrate differ between material science and biological science?

• In material science, it is a chemical compound; in biological science, it is a type of enzyme.

• In material science, it is a type of microorganism; in biological science, it is a type of plant.

• In material science, it is a nutrient source; in biological science, it is a surface for coating.

• In material science, it is a surface for coating; in biological science, it is material at the bottom of water bodies.
