Question
- A. Use the electron transport chain trace to explain energy transfer in cells; link the data to ATP production, reduced coenzymes, proton gradients, carbon fixation or substrate-level phosphorylation as required by the objective.
- B. Use only the phrase 'energy transfer in cells' and do not interpret the electron transport chain trace.
- C. Alter oxygen availability, mitochondrial mass and substrate supply and timing together, then claim the result is valid without evaluation.
- D. Describe energy as being made from nothing instead of transferred through ATP, reduced coenzymes or chemical bonds.
Answer
The correct answer is: Use the electron transport chain trace to explain energy transfer in cells; link the data to ATP production, reduced coenzymes, proton gradients, carbon fixation or substrate-level phosphorylation as required by the objective.
Explanation
This is correct because it uses a distinct experimental context and links evidence to Calculate gross production, net production and respiratory loss where data are provided. For practical work it names independent variable, dependent variable and controlled variable, then evaluates reliability and uncertainty.
Common mistake
Energy and ecosystems common mistake 1
Giving a vague answer instead of directly addressing: Calculate gross production, net production and respiratory loss where data are provided..
Answer by clearly explaining how to calculate gross production, net production and respiratory loss where data are provided..
