Exam points

  • Explain how ATP hydrolysis supplies energy for active transport, including membrane pumps that move ions against concentration gradients.
  • Relate ATP use to movement and molecular motors, such as actin–myosin contraction, chromosome movement and cilia/flagella.
  • Identify ATP-dependent anabolic synthesis and other cellular work, linking ATP conversion to the specific life process.
