METABOLISM

Question 1

• Synthesis of compounds from smaller raw materials
• Endergonic and divergent process

Answer 1

Anabolic

Question 2

• Breakdown of larger molecules
• Usually oxidative reactions
• Exergonic and convergent process
• Produces reducing equivalents and ATP mainly via the respiratory chain

Answer 2

Catabolic

• Link between anabolic and catabolic pathways
• Example: Citric Acid Cycle
