Chapter 9.3 Anaerobic respiration Flashcards
What is the equation for anaerobic respiration?
Glucose ==> lactic acid (energy transferred to the environment)
What is then definition of anaerobic respiration?
Anaerobic respiration is an exothermic reaction in which glucose is broken down in the absence of oxygen to produce lactic acid in animals and ethanol and carbon dioxide in plants and yeast. A small amount of energy is transferred for the cells.
What is the definition of an oxygen debt?
An Oxygen Debt is The amount of extra oxygen needed by muscle tissue to oxidise lactic acid following exercise. (During vigorous exercise, the body needs a lot more energy, and therefore has to get more oxygen into the muscle tissue where energy is needed. Anaerobic respiration produces an oxygen debt.)
What is the equation for fermentation?
Glucose ==> ethanol + carbon dioxide (energy transferred to the environment)
C6H12O6 → 2 C2H5OH + 2 CO.
Describe four benefits of anaerobic respiration.
Such places include deep water, soil, and the digestive tracts of animals such as humans. E. coli bacteria are anaerobic bacteria that live in the human digestive tract.
