What is the structure of enzymes and how do they function?

Enzymes are proteins that act as catalysts in biochemical reactions. They have a unique three-dimensional structure that allows them to bind to specific substrates.

Can you explain the active site and its role?

The active site is a specific region on the enzyme where substrate molecules bind. It is crucial for the enzyme's catalytic activity.

What factors can affect enzyme activity?

Enzyme activity can be affected by temperature, pH, substrate concentration, and the presence of inhibitors or activators.

How do enzymes lower the activation energy of reactions?

Enzymes lower activation energy by stabilizing the transition state, making it easier for the reaction to occur.

Are all enzymes proteins?

Most enzymes are proteins, but some RNA molecules, known as ribozymes, can also have catalytic activity.
