The cards Question What is breathing? Tap to flip Answer The process in which air moves in and out of the lungs. Question Why do cells need oxygen from the air? Tap to flip Answer For cellular respiration, to provide energy for life processes. Question What waste product does cellular respiration produce? Tap to flip Answer Carbon dioxide. Question In gas exchange, which way does oxygen diffuse? Tap to flip Answer From the lungs into the blood. Question In gas exchange, which way does carbon dioxide diffuse? Tap to flip Answer From the blood into the lungs. Question Are breathing and respiration the same thing? Tap to flip Answer No: breathing moves air in and out of the lungs; respiration is a chemical process in cells. Question What is the human gas exchange system? Tap to flip Answer A group of organs that work together to enable us to breathe. Question What is inhalation? Tap to flip Answer Breathing in. Question What is exhalation? Tap to flip Answer Breathing out. Question What creates the pressure of a gas in a container? Tap to flip Answer Its molecules colliding with the walls of the container. Question What is vital capacity? Tap to flip Answer The maximum volume of air that can be breathed out after breathing in fully. Question In science, what makes a measurement more accurate? Tap to flip Answer Being closer to the true value. Question What is an estimate? Tap to flip Answer An approximate (rough) value of a quantity, obtained without taking accurate measurements. Question What measurement can an estimate of lung volume be calculated from? Tap to flip Answer Vital capacity. Question What are alveoli? Tap to flip Answer Tiny air sacs in the lungs that carry out gas exchange. Question What is a capillary? Tap to flip Answer A narrow blood vessel that allows the exchange of substances between tissues and blood. Question What is diffusion? Tap to flip Answer The movement of particles from a high concentration to a low concentration. Question In the lungs, between what does gas exchange take place? Tap to flip Answer Air in the alveoli and blood in the capillaries. Question Why are there millions of alveoli in the lungs? Tap to flip Answer To increase the surface area for gas exchange. Question Why are the walls of the alveoli one cell thick? Tap to flip Answer To give a short diffusion distance for gas exchange. Question Why are the alveoli surrounded by capillaries carrying blood? Tap to flip Answer To maintain a concentration gradient for gas exchange. Question What is cellular respiration? Tap to flip Answer A chemical process that uses glucose, from food, as a fuel to provide energy for life processes. Question What is glucose? Tap to flip Answer A sugar that cells use as fuel for cellular respiration. Question In which cell organelles does cellular respiration take place in animals and plants? Tap to flip Answer Mitochondria. Question Why does cellular respiration happen in all living organisms all the time? Tap to flip Answer To provide the energy that keeps them alive. Question Do plants respire? Tap to flip Answer Yes. Question Which gas does aerobic cellular respiration require? Tap to flip Answer Oxygen. Question Which gas is a product of aerobic cellular respiration? Tap to flip Answer Carbon dioxide. Question Where in animal, plant and fungi cells does aerobic cellular respiration take place? Tap to flip Answer In the mitochondria and cytoplasm. Question Which cells have more mitochondria? Tap to flip Answer Cells that do a lot of work and so require more energy. Question What is cytoplasm? Tap to flip Answer The jelly-like substance inside a cell where its chemical reactions take place. Question Is aerobic cellular respiration a single chemical reaction? Tap to flip Answer No: it is a series of chemical reactions. Question Does anaerobic cellular respiration use oxygen? Tap to flip Answer No. Question What does anaerobic cellular respiration produce in humans? Tap to flip Answer Lactic acid. Question What can lactic acid cause in humans? Tap to flip Answer Muscle cramps. Question Where in a cell does anaerobic cellular respiration take place? Tap to flip Answer Only in the cytoplasm; it does not involve the mitochondria. Question How does anaerobic cellular respiration compare with aerobic in the energy it provides? Tap to flip Answer It provides less energy, but provides it more quickly. Question What is a microorganism? Tap to flip Answer A living organism made up of one or a small number of cells. Question What does anaerobic cellular respiration produce in microorganisms? Tap to flip Answer Carbon dioxide and ethanol (a type of alcohol). Question What is anaerobic cellular respiration in microorganisms also called? Tap to flip Answer Fermentation. Question Give one useful product that humans make using fermentation in microorganisms. Tap to flip Answer E.g. bread or yogurt.

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.
