Science — AI-generated practice question

ATP (Adenosine Triphosphate) is a molecule produced during respiration when organic compounds like glucose are broken down.

It is called the 'energy currency' of the cell because it stores energy released during respiration and supplies it for various cellular reactions whenever needed — just as currency is used to purchase goods and services.

• The passage directly states: "organic compounds such as glucose are broken down to provide energy in the form of ATP. ATP is used to provide energy for other reactions in the cell."
• The "energy currency" analogy is the key conceptual point examiners expect — ATP is earned (produced in respiration) and spent (used in cell activities), like money.
• For 2 marks: 1 mark for defining ATP, 1 mark for explaining the currency analogy. Keep it concise.
