AFour steps
BSix steps
CEight steps
DTen steps
Answer & Solution
Correct answer: C. Eight steps
1. The citric acid cycle is described as having eight steps.
2. Those eight steps are a series of redox, dehydration, hydration and decarboxylation reactions.
3. They produce two carbon dioxide molecules, one high-energy nucleotide and reduced electron carriers.
4. Ten is the count for glycolysis, which is the usual mix-up.
