Exam points

  • Explain how ATP captures energy from respiration and distributes small, usable transfers to energy-requiring cellular processes.
  • Explain that ATP hydrolysis to ADP and phosphate releases manageable energy for cellular work, while ATP is rapidly regenerated.
  • Relate ATP solubility and stability in the cytoplasm to its role as a universal cellular energy currency.
