Exam points

  • Explain how a pump uses ATP and a conformational change to move a specific solute against its concentration gradient.
  • Identify the role of protein specificity in active transport across a membrane.
  • Distinguish ATP-driven pumping from passive channel or carrier movement in an experimental example.
