(a) What are the intermediate products of anaerobic respiration in an active muscle?
(b) Which of them is associated with oxygen debt?
(c) In what way is this product associated with the 'oxygen debt?
(a) In an active muscle, the intermediate products of anaerobic respiration are pyruvic acid and lactic acid.
(b) lactic acid is associated with oxygen debt.
(c) lactic acid which accumulates in the muscles has to be taken to the liver and oxidised even after the exercise has finished.
