• The term for metal ions that assist enzymes during the catalysis reaction -
✓✓cofactors
• What is catabolism? -✓✓The process of breaking down larger molecules into
useful energy sources
• Upon cellular injury, which metabolic process is involved during the growth and

• An organism that derives its energy by removing electrons from elemental sulfur
would be classified as a ____________ -✓✓Lithotroph
• Describe the energy transfer process relative to both ADP and ATP -✓✓ATP has
the energy (phosphate group) to donate, and ADP can accept energy in the form of
