8 Questions
What are enzymes?
Enzymes are proteins that function as biological catalysts.
What is the active site of an enzyme?
The active site is where smaller molecules fit into the enzyme.
Explain the lock and key hypothesis of enzyme-substrate interaction.
The lock and key hypothesis states that the shape of the active site matches the shape of the substrate molecules.
What happens if enzymes are exposed to extremes of pH or high temperatures?
The shape of their active site may change, leading to denaturation.
Why are enzymes considered highly specific?
Enzymes are highly specific because the shape of their active site matches the shape of the substrate molecules.
How do enzymes speed up chemical reactions?
Enzymes speed up reactions by lowering the activation energy needed for the reaction to occur.
Explain the role of enzymes in joining smaller substrate molecules together.
Enzymes join smaller substrate molecules into larger ones.
What term is used to describe the change in an enzyme's active site shape when exposed to extreme conditions?
Denaturation
Explore the world of enzymes, proteins that act as biological catalysts by speeding up chemical reactions without being altered. Learn about the lock and key hypothesis, where enzymes have specific 3D shapes that allow molecules to fit into their active sites.
