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 12

Calculate the total number of ATP molecules produced from one molecule of glucose during aerobic respiration in eukaryotic cells.
Describe the role of FADH2 in cellular respiration.
Describe the role of mitochondria in cellular respiration.
