Question
- A. Organisms need energy for chemical reactions that build larger molecules.
- B. Students often state that organisms need energy only for movement, neglecting other essential processes.
- C. It is not correct that organisms need energy for chemical reactions that build larger molecules.
- D. The idea only requires memorising the topic title for Respiration.
Answer
In this question, Organisms need energy for chemical reactions that build larger molecules. is correct It stays aligned to the exact wording and meaning of the objective.
Explanation
In AQA-style practice, the correct answer must match the objective closely and use the science rather than filler wording. That is why Organisms need energy for chemical reactions that build larger molecules. is the best option here. Linking the idea to in Aerobic and anaerobic respiration, energy refers to the capacity to do work, which organisms need for various chemical reactions. This matters in Respiration because it supports the learning objective to state that organisms need energy for chemical reactions that build larger molecules. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions keeps the explanation specific.
Common mistake
Misunderstanding Energy Needs
Students often state that organisms need energy only for movement, neglecting other essential processes.
Emphasize that organisms require energy for various chemical reactions, including those that build larger molecules, not just for movement.
