I WONDER - What Are Metabolic Reactions?

The video tutorial explains anabolic and catabolic reactions. Anabolic reactions are likened to a construction crew, building complex molecules from simpler ones and requiring energy input, essential for growth and repair. Catabolic reactions are compared to a demolition crew, breaking down complex molecules and releasing energy, which is then used to fuel anabolic reactions and other cellular activities. Enzymes are crucial in both reactions, ensuring they proceed correctly.

What is the primary function of anabolic reactions in the body?

• To store energy

• To break down complex molecules

• To release energy

• To build complex molecules from simpler ones

Which type of reaction is responsible for breaking down complex molecules?

• Photosynthesis

• Catabolic reactions

• Anabolic reactions

• Fermentation

What happens to the energy released during catabolic reactions?

• It is stored as fat

• It is used to fuel anabolic reactions

• It is lost as heat

• It is converted into water

What role do enzymes play in metabolic reactions?

• They convert energy into molecules

• They ensure reactions proceed at the right speed and direction

• They provide energy for reactions

• They slow down reactions

Why are enzymes crucial for both anabolic and catabolic reactions?

• They increase the temperature of reactions

• They act as a source of energy

• They break down enzymes

• They regulate the speed and direction of reactions
