1. Cellular Respiration

2. Takes place in the mitochondria. The mitochondria is known as the “powerhouse” of the cell because it produces the energy needed for cellular functions. http://4.bp.blogspot.com/- VuGbfaqr0I0/TY9cuCY6nnI/AAAAAAAAAfA/1uqzNWDEKk A/s1600/mitochondria.jpg http://upload.wikimedia.org/wikipedia/commons/thumb/0/0c/Animal_mitochondri on_diagram_en_(edit).svg/400px- Animal_mitochondrion_diagram_en_(edit).svg.png

3. Cellular Respiration There are two types of cellular respiration. Aerobic respiration requires oxygen. Anaerobic respiration does not require oxygen. Aerobic and anaerobic respiration differs in terms of the amount of energy that is produced.

4. Aerobic Respiration Oxygen is always required. The molecules of food (Glucose)are broken down to obtain energy in the form of adenasine triphosphate (ATP).energy Carbon dioxide and water are also bi- products.

6. Aerobic Respiration A lot of energy is produced during aerobic respiration, which may be as high as 38 ATP molecules for every glucose molecule. This means that during aerobic respiration only one molecule of glucose will produce about thirty-eight energy units.

7. Anaerobic Respiration In plain language, anaerobic means where there is no air and thus anaerobic respiration is a term used for the respiration that occurs without the use of oxygen. Anaerobic respiration produces less energy when compared with the process of aerobic respiration. This can be best illustrated with the fact that during the anaerobic respiration only two molecules of ATP are yielded for one glucose moleculeglucose molecule

8. Anaerobic Respiration Another name for anaerobic respiration is fermentation. Alcohol is a byproduct of anaerobic respiration.

9. Anaerobic Respiration Mitochondria Glucose 2 ATP + Alcohol and CO 2 Lactic Acid

10. Anaerobic Respiration Generally anaerobic respiration is always used by the primitive living organisms, which live in places where oxygen is missing, like muddy bottom of a river. In such places, the organism survives without depending to a large extent on oxygen. These habitats are known as anoxic.

11. Anaerobic Respiration What is lactic acid and why does it build up in our muscles? Follow the directions on your worksheet to learn more about anaerobic respiration and lactic acid.
