Aerobic Respiration

• Aerobic respiration happens in the presence of oxygen and releases more energy than anaerobic respiration.
• Aerobic respiration is the the chemical reaction that transfers energy from glucose.
• In aerobic respiration the glucose reacts with oxygen.
• This reaction transfers energy to your cells.
• Carbon dioxide and water is produced as a waste product
• Word Equation for Aerobic respiration is -

  Glucose + Oxygen --> Carbon dioxide + Water
• HOW DOES GLUCOSE GET INTO THE CELL-

  
  

  Food is digested, sugar is absorbed into the blood. It is carried in the plasma around the body. The sugar diffuses into the cells.
• HOW DOES OXYGEN GET INTO CELLS -

  The air we breathe in contains oxygen which is absorbed in our lungs. The Haemoglobin carries the oxygen in our blood to our cells, and then releases it. The oxygen diffuses into the cell.

   
• HOW DOES CARBON DIOXIDE LEAVE THE BODY-

  The carbon dioxide leaves the cell, it is carried by the plasma in the blood to the lungs. In the lungs the carbon dioxide leaves the lungs and is exhaled in the air that leaves the body.

   
• After food is digested, what happens to te sugar in our blood ?

  it gets absorbed into the blood
• Oxygen is needed to break down the lactic acid in muscles. Because of this, people continue to breathe heavily for a short period after excercise in order to get enough oxygen to the muscle cells.
