Questions and Answers

Where does the chemical energy in food molecules come from?

  • From the ATP molecule
  • By the addition of a phosphate group
  • Directly from the food you eat
  • Through a series of chemical reactions breaking down the molecules (correct)

    • What is the main energy carrier molecule that cells use for their processes?

  • ATP (correct)
  • Carbohydrates
  • Lipids
  • ADP

    • How is energy released from ATP for cellular processes?

  • When a phosphate group is removed from the molecule (correct)
  • Through a reaction that breaks a bond between carbon-based molecules
  • When lipids are broken down
  • By adding a phosphate group
