12. Any surface adapted to exchange the gas carbon dioxide for oxygen by the process of diffusion is considered a gaseous exchange surface in man
 * 1) Term 3 http://www.tutorvista.com/content/biology/biology-ii/respiration/respirationindex.php
 * 2) **respiration**- __aerobic (with oxygen) and anaerobic (without oxygen) release of energy from food__. respiration in the mitochondrion v.s. in the cytoplasm. All are enzyme controlled reactions and all liberate energy to do work
 * 3) aerobic respiration (in the mitochondrion) - **Glucose** + **6 oxygen = 6 carbon dioxide + 6 water + energy**
 * 4) **__energy must be packaged in a safe and usable form__ in cells called __ATP adenosine triphosphate.__ **
 * 5) **energy from one glucose molecule converts 38 ADP + P to 38 ATP **
 * 6) **2ATP molecules are used in the process of aerobic resiration therefore a net 36ATPs are released to do work about a cell.**
 * 7) anaerobic respiration (in the cytoplasm of animal cells) - **glucose = lactic acid + little energy when oxygen is in short supply but energy to do work is demanded by the cell.**
 * 8) ** lactic acid (unburnt fuel) __can only be removed by completing the oxidation reaction using oxygen__ thus even after excercise we have a high breathing and heart rate to pay back this oxygen debt .**
 * 9) **What causes muscle fatigue and pain? - Lactic acid**
 * 10) ** oxygen debt is explained as the oxygen needed after strenuous exercise to complete the oxidation of lactic acid (convert) to carbon dioxide and water.**
 * 11) anaerobic respiration ( in the cytoplasm of yeast cells) - fermentation = **alcohol + carbon dioxide + little energy**. alcohol used to produce rum, wine, whisky etc. carbon dioxide cause bread to rise.
 * 12) anaerobic respiration by bacteria produces - bio gas (methane) from desd organic matter, cheese, sour cream, yogurt and frozen yogurt from milk.
