Bio Unit 3 - Concept 1 - Reactions and Enzymes

Front

What is a catabolic reaction?

Back

A catabolic reaction is a type of metabolic reaction where larger molecules are broken down into smaller molecules, releasing energy in the process.

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 an endothermic reaction?

Back

An endothermic reaction is a chemical reaction in which the products store more energy than the reactants, absorbing energy from the surroundings.

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 metabolism?

Back

Metabolism refers to all of the chemical reactions that occur within each cell of an organism, including both catabolic and anabolic reactions.

Front

What is an anabolic reaction?

Back

An anabolic reaction is a type of metabolic reaction where smaller molecules are combined to form larger molecules, usually requiring energy.

Front

What is the difference between reactants and products?

Back

Reactants are the starting substances in a chemical reaction, while products are the substances formed as a result of the reaction.

Front

What is a catalyst?

Back

A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process.

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes are biological catalysts that speed up biochemical reactions by lowering the activation energy required for the reaction to occur.

Front

What is activation energy?

Back

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