Aerobic respiration

How do cells get what they need for aerobic respiration?

• All organisms are made up of cells and energy is needed to power the many processes a cell carries out
• This energy is released into a series of enzyme-catalysed reactions known as respiration
• Respiration is the release of energy from food molecules that acts as fuel for the cells

• Cells that are more active have higher energy requirements, during exercise the muscles contract to cause movement, and this requires lots of energy from respiration
• Growing and dividing the cells also need a lot of energy to power the building of new cell materials
• In aerobic respiration oxygen is used to release energy from molecules such as glucose. The glucose and oxygen are converted into carbon dioxide and water and energy is released…
