respiration provides energy within cells

• what is meant by respiration being a catabolic process


  it involves a series of enzyme-catalysed reactions in cells
• give two examples of energy rich substrates


  glucose and fatty acids
• by what process do glucose and fatty acids release energy


  by hydrolysis
• what two ways can energy be produced as by glucose and fatty acids being hydrolysed


  ATP and heat energy
• give three examples of bonds that are broken by enzymes to produce ATP


  c-c , c-h and c-oh bonds
• What is aerobic respiration?


  this is the release of large quantities of ATP energy from glucose or another organic substrate in the presence of oxygen
• What is anaerobic respiration?


  this is the release of small amounts of ATP in the absence of oxygen
• what is produced as a bi product in aerobic respiration


  carbon dioxide
• what is produced as bi products in anaerobic respiration in animal cells


  lactate
• what is produced as a bi product in anaerobic respiration in yeast cells


  carbon dioxide and ethanol
• what is meant by dehydrogenation


  the removal of Hydrogen by dehydrogenase
• what is meant by carboxylation


  the removal of carbon dioxide by an decarbocylase
