Statement I: NADH is oxidised to NAD+ rather slowly in fermentation and very vigorously in aerobic respiration.
Statement II: In aerobic respiration, only glucose is oxidised, no other alternative substrates enter in the pathway.

Important Questions on Respiration in Plants

Reason (): Respiratory pathway is involved in both anabolism and catabolism.

For the Amphibolic pathway, choose the correct option of true assertions from the given assertions.
(I) Lipid enters the first stage of the respiratory pathway.
(II) The conversion of carbohydrates into glucose, before their entry into respiration is not compulsory.
(III) Protein enters into the respiratory pathway in the form of Pyruvic acid.
(IV) Oxidation and formation of lipid and protein, these two events take place.
