Cellular Energy and Metabolism starts at 8 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Cellular Energy and Metabolism.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 9

Describe the main difference between aerobic and anaerobic respiration.
Describe what happens to glucose during glycolysis.
Explain the relationship between photosynthesis and cellular respiration.
Explain the role of chloroplasts in plant cells.
Explain why plants need both mitochondria and chloroplasts.
