  • What is the fate of glucose in the respiratory pathway?

  • It is directly respired without any conversion.
  • It does not enter the respiratory pathway at all.
  • It enters the respiratory pathway after being broken down into glycerol and fatty acids.
  • It is usually first converted into glucose before being used for respiration. (correct)
  • Which pathway involves the complete degradation of glucose to CO2 and H2O?
