Questions and Answers

What is the role of ATP in cellular processes?

  • Providing energy for both energy-consuming and energy-releasing reactions (correct)
  • Storing genetic information for cellular processes
  • Regulating the expression of genes in prokaryotic cells
  • Facilitating cell division in eukaryotic cells

Why is ATP compared to a rechargeable battery for cellular processes?

  • Because ATP has a long half-life in the cell
  • Because ATP is only involved in energy-releasing reactions
  • Because the bond in ATP is easily broken and reformed, releasing energy for cellular work (correct)
  • Because ATP is only used once in cellular processes

Why does ATP contain a high potential energy?

  • Due to the presence of multiple chemical bonds (correct)
  • Because it is a stable molecule
  • Because it requires a large input of activation energy
  • Due to its low reactivity in the cell
