Question

krebs cycle with reaction

Answer 1

The reaction is the oxidation of an alcohol to a ketone to make oxaloacetic acid. The coenzyme NAD+ causes the transfer of two hydrogens and 2 electrons to NADH + H+. This is a final entry point into the electron transport chain.

Answer 2

Krebs cycle was described by Sir Hans Krebs in 1937,1940 . It is also known as citric acid cycle or TCA(Tricarboxylic acid cycle). During this cyclical pathway acetyl Co-A is oxidised with the help of O2 in a series of reactions producing CO2 and water.
Co-A + O2 = CO2 + Water
