Questions and Answers

Which term refers to the breakdown of large molecules into smaller ones?

  • Synthesis
  • Catabolism (correct)
  • Anabolism
  • Metabolism

What is the main difference between catabolism and anabolism?

  • Energy is released in both catabolism and anabolism
  • Energy is absorbed in both catabolism and anabolism
  • There is no energy change in either catabolism or anabolism
  • Energy is released in catabolism and absorbed in anabolism (correct)

What is a metabolic pathway?

  • A series of consecutive reactions forming a cycle (correct)
  • A single reaction that breaks down molecules
  • A random set of reactions with no specific order
  • An isolated reaction with no energy changes
