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)
