Anaerobic Respiration: Observing Yeast's Oxygen-Free Energy Production
We use yeast to let us observe anaerobic respiration. The yeast is added to warm water and glucose. A layer of oil is placed over the solution so that no oxygen is available. The solution starts to bubble and the gas produced passes...

How To Reduce Carbon Dioxide In The Air
Through photosynthesis, plants take in carbon dioxide from the air and split it and use it (and water) to make carbohydrates. So surely plants can help us reduce carbon dioxide in the air? Possibly... But equally, the carbon in plants is...

BIOLOGY - Physiology - Anaerobic Respiration
Sometimes animals and plants cannot get enough oxygen to respire aerobically, such as during intense exercise, but they still need to respire to survive. After all, everything relies on respiration for energy. Luckily there is a back-up...
