The cards Question What is cellular respiration? Tap to flip Answer An exothermic chemical process that transfers energy for life processes, using glucose as a fuel. Question What does 'exothermic' mean? Tap to flip Answer A chemical process that transfers energy to its surroundings. Question What does 'aerobic' mean? Tap to flip Answer A process that requires oxygen. Question What are mitochondria? Tap to flip Answer Sub-cellular structures involved in aerobic cellular respiration. Question How often does cellular respiration happen in living organisms? Tap to flip Answer Continuously, to transfer the energy needed for life processes. Question Which substance is the fuel for cellular respiration? Tap to flip Answer Glucose. Question Where in eukaryotic cells does aerobic cellular respiration take place? Tap to flip Answer In the mitochondria. Question Where in prokaryotic cells does aerobic cellular respiration take place? Tap to flip Answer In the cytoplasm, as prokaryotic cells have no mitochondria. Question Does cellular respiration create energy? Tap to flip Answer No; it transfers energy. Question What does 'anaerobic' mean? Tap to flip Answer A process that does not require oxygen. Question What is lactic acid? Tap to flip Answer A product of anaerobic cellular respiration in humans that causes muscle cramps. Question What is oxygen debt? Tap to flip Answer The amount of oxygen needed to remove lactic acid from the body after exercise. Question What is fermentation? Tap to flip Answer Anaerobic cellular respiration in yeast, producing ethanol and carbon dioxide. Question Where in the cell does anaerobic cellular respiration take place? Tap to flip Answer Only in the cytoplasm; it does not involve mitochondria. Question How does anaerobic respiration compare with aerobic respiration in energy transferred and speed? Tap to flip Answer It transfers less energy, but more quickly. Question Do plants respire? Tap to flip Answer Yes; plants respire as well as photosynthesise. Question What is an independent variable? Tap to flip Answer The factor that is changed in an experiment. Question What is a dependent variable? Tap to flip Answer The factor that is measured in an experiment. Question What is random error? Tap to flip Answer Error that makes results differ by different amounts, due to a factor other than the independent variable. Question What is systematic error? Tap to flip Answer Error that makes measurements differ from the true value by the same amount each time. Question Which gas do living yeast cells in alginate beads produce by cellular respiration? Tap to flip Answer Carbon dioxide. Question Why are other variables controlled in an experiment? Tap to flip Answer To increase the validity of the results. Question From which part of the meniscus should the volume of gas in a measuring cylinder be read? Tap to flip Answer The bottom of the meniscus. Question What is rate? Tap to flip Answer A measure of how much change occurs per unit of time. Question How is the rate of respiration calculated from gas collected in a measuring cylinder? Tap to flip Answer Volume of gas collected divided by the time. Question What is a substrate? Tap to flip Answer The substance that fits into an enzyme's active site. Question What is an enzyme? Tap to flip Answer A biological catalyst. Question What is the active site of an enzyme? Tap to flip Answer The part of the enzyme where the substrate binds. Question Can an enzyme act on many different substrates? Tap to flip Answer No; each enzyme has a specific substrate, because only that substrate fits its active site. Where this deck sits in the curriculum Curriculum National Curriculum for England Stage GCSE (Years 10–11) Course GCSE Biology Unit Aerobic and anaerobic cellular respiration Exam boards AQA, Edexcel, OCR Tiers foundation and higher England's National Curriculum sets what is taught; the units and their order are Oak National Academy's.

How this deck was checked On 2026-11-02, every card was compared with its source: the lessons of Oak National Academy, a public body funded by England's Department for Education that publishes lessons for the national curriculum. Because the cards come from those lessons, no second source was sought. The comparison was done automatically, not by a teacher, so a card can still be wrong. Flash Feed is not affiliated with any source named here.
