Aerobic respiration is a ________ reaction
Exothermic
Aerobic respiration equation
C6H12O6 + 6O2 �> 6CO2 + 6H2O (energy transferred to environment)
Transferred energy uses
Builds larger molecules from smaller ones
Muscle contractions in animals
A constant temperature
Active transport
Proteins being formed
anaerobic respiration equation
Glucose �> lactic acid (energy transferred to environment)
Lactic acid need to be broken down by...
Extra oxygen, creating an oxygen debt
Metabolic reactions
Glucose to starch, glycogen or cellulose
Fatty acids and glycerol to lipids
Glucose and nitrate ions to amino acids
Amino acids to protein
Respiration
Photosynthesis
Excess to proteins to urea
Prime Role of the liver
Amino acids �> (by deamination (removal of amino group))ammonia �>
Urea �> (in blood to kidneys) urine
Functions of liver
Poisonous substances (ethanol) detoxified and excreted
Old red cells broken down to form new ones
Lactic acid broken down into glucose
