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 11
A cell is placed in an environment with no oxygen. Which process will allow it to continue producing ATP?
A scientist observes that yeast cells produce ethanol and carbon dioxide in the absence of oxygen. What type of metabolism is occurring?
A student measures the rate of oxygen consumption in germinating seeds. What cellular process is being measured?
Describe the role of ATP synthase in cellular respiration.
Describe the role of mitochondria in cellular respiration.
