Enzymes

Front

What is the role of enzymes in chemical reactions?

Back

Enzymes speed up chemical reactions by lowering the activation energy required for the reaction to occur.

Front

What is a catalyst?

Back

A catalyst is a substance that speeds up a chemical reaction without being consumed in the process.

Front

What happens to enzymes at high temperatures?

Back

Enzymes can denature, meaning their shape changes and they lose their functionality.

Front

What is the active site of an enzyme?

Back

The active site is the specific region on an enzyme where the substrate binds and the reaction occurs.

Front

What is a substrate in the context of enzymes?

Back

A substrate is the reactant molecule that an enzyme acts upon.

Front

What is denaturation in enzymes?

Back

Denaturation is the process where an enzyme loses its three-dimensional structure due to external factors like heat or pH changes.

Front

How do enzymes affect the activation energy of a reaction?

Back

Enzymes lower the activation energy, making it easier for the reaction to occur.

Front

What factors can affect enzyme activity?

Back

Factors include temperature, pH, substrate concentration, and the presence of inhibitors or activators.

Front

What is an enzyme inhibitor?

Back

An enzyme inhibitor is a substance that decreases enzyme activity by binding to the enzyme and preventing substrate binding.

Front

What is enzyme specificity?

Back

Enzyme specificity refers to the ability of an enzyme to choose exact substrates from a group of similar chemical molecules.
