What Is Common to All of the Oxidation Reactions in the Krebs

question 40

Multiple Choice

What is common to all of the oxidation reactions in the Krebs cycle?

• A)They all lead to the generation of NADH.
• B)They are all decarboxylation reactions.
• C)They are all characterized by a loss of electrons from an organic molecule coupled to the reduction of an electron acceptor.
• D)They all lead to substrate-level phosphorylation of ADP to generate ATP. While all of the oxidation reactions are characterized by the donation of electrons from an organic molecule to an electron acceptor, they are not all decarboxylation reactions, nor do they all involve the generation of NADH.The third oxidation reaction is not a decarboxylation reaction, and involves the generation of FADH₂.None of the oxidation reactions directly induce substrate-level phosphorylation of ADP.
