Sustrato

The video tutorial explains the concept of substrates in different contexts. It begins with a discussion on coating deposition, followed by an explanation of substrates in biochemistry, where they are substances on which enzymes act. Finally, it covers substrates in biology, referring to materials like silt and stones found at the bottom of water bodies such as riverbeds.

In the context of coatings, what is a substrate?

• A chemical that reacts with paint

• The surface on which a coating is applied

• A type of paint used for protection

• A tool used for applying paint

In biochemistry, what role does a substrate play?

• It is a catalyst for enzyme activity

• It is a byproduct of enzyme reactions

• It is the substance on which an enzyme acts

• It is a type of enzyme

Which of the following best describes a substrate in biology?

• A type of aquatic plant

• A type of fish habitat

• The material at the bottom of a body of water

• A layer of algae on rocks

What is an example of a substrate in a riverbed?

• Algae

• Silt and stones

• Water

• Fish

How does the concept of a substrate differ between biochemistry and biology?

• In biochemistry, it is a habitat; in biology, it is a chemical

• In biochemistry, it is a surface; in biology, it is a chemical

• In biochemistry, it is a chemical; in biology, it is a surface

• In biochemistry, it is a surface; in biology, it is a habitat
