Cells transfer energy through reactions - Paper 1
Read the information, then answer the questions. An adult may read the instructions aloud. Show your working where asked.
Read before answering
Focus: a germinating seed cell, with glucose and oxygen available. School aerobic-respiration summary: glucose + oxygen -> carbon dioxide + water, with energy transferred for cell processes. It is a cellular process, distinct from ventilation. Evaluate the misconception using this model, not personal health measurements.

- Name the reactants and products in the aerobic model for a germinating seed cell.
- Correct this claim about a germinating seed cell: 'A seed without leaves cannot transfer energy by respiration.'
- Would oxygen being available alone prove how fast a germinating seed cell is respiring? Explain.
