Respiration

• Respiration is a series of enzyme controlled reactions that expel energy from glucose.
• In aerobic respiration, pyruvate enters mitochondria to be oxidised further
• The first stage of respiration takes place in the cytoplasm, where glucose is converted into pyruvate by glycolysis
• Glycolysis produces two molecules of ATP per glucose molecule
• Glycolysis produces ATP without the use of oxygen
• The chemical released form the breakdown of glucose is known as ATP.
• The greater the energy requirements of a cell, the greater the number of Mitochondria present in the cell.
• Fermentation is the process of converting glucose into ethanol and carbon dioxide which can only occur in the absence of oxygen.
• A Respirometer is a device used to measure the rate of gas exchange in a living organism.
• ATP is the acronym for adenosine triphosphate, which is the energy currency of the cell.
