Identify the correct statement.

Easy

A

Fermentation liberates all the energy available in each sugar molecule
B

In the absence of O₂, fermentation regenerates the FAD⁺ needed for glycolysis.
C

If the provided oxygen is labelled with ¹⁸O, the liberated water in aerobic respiration shows radioactivity.
D

The reactions catalysed by pyruvic dehydrogenase complex requires the participation of several coenzymes, including FAD⁺ and Coenzyme A.

Solution

If oxygen is labelled with ¹⁸O, water molecules liberated show radioactivity as glycolysis, Krebs cycle and oxidative phosphorylation are completed. This is because O₂ is the terminal electron acceptor. It accepts electrons and forms H₂O.
Fermentation does not liberate all the energy available in each sugar molecule
In absence of O₂, fermentation regenerates the NAD⁺ needed for glycolysis
The reactions catalysed by pyruvic dehydrogenase require the participation of several coenzymes, including NAD⁺ and Coenzyme A.
