Enzymes & Chemical Reactions

Front

What is an enzyme?

Back

An enzyme is a type of protein that acts as a catalyst to speed up chemical reactions in biological processes.

Front

What is activation energy?

Back

Activation energy is the minimum amount of energy required to start a chemical reaction.

Front

What happens to reaction rates when temperature increases?

Back

An increase in temperature generally increases the rate of a chemical reaction.

Front

What is a competitive inhibitor?

Back

A competitive inhibitor is a substance that competes with the substrate for binding to the active site of an enzyme, thereby reducing the rate of the reaction.

Front

What is a co-enzyme?

Back

A co-enzyme is a non-protein molecule that assists enzymes in catalyzing reactions, often by helping to transfer electrons or functional groups.

Front

What are reactants?

Back

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

Front

What are products?

Back

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

Front

What is an endothermic reaction?

Back

An endothermic reaction is a type of chemical reaction that absorbs energy from its surroundings.

Front

What is an exothermic reaction?

Back

An exothermic reaction is a type of chemical reaction that releases energy, usually in the form of heat.

Front

What is the role of enzymes in chemical reactions?

Back

Enzymes lower the activation energy required for a reaction, thus increasing the reaction rate.
