Chemical Reactions and Enzymes

Front

What are reactants in a chemical reaction?

Back

Reactants are the starting substances that undergo a chemical change in a reaction.

Front

What are products in a chemical reaction?

Back

Products are the substances that are formed as a result of a chemical reaction.

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 does it mean to denature a protein?

Back

Denaturing a protein means changing its molecular conformation, which destroys its function.

Front

What is the active site of an enzyme?

Back

The active site is the 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 upon which an enzyme acts.

Front

What is activation energy?

Back

Activation energy is the minimum energy required for a chemical reaction to occur.

Front

How do enzymes affect activation energy?

Back

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

Front

What is the role of coenzymes in enzymatic reactions?

Back

Coenzymes are organic molecules that assist enzymes in catalyzing reactions.

Front

What is the difference between a catalyst and a coenzyme?

Back

A catalyst speeds up a reaction, while a coenzyme is a specific type of catalyst that is an organic molecule.
