The Krebs cycle is a cyclic series of chemical reactions during which:
Correct answer: A. Oxidation process is completed
- A. Oxidation process is completed
- B. Decarboxylation process is completed
- C. Reduction process is completed
- D. Energy consuming process is completed
Explanation
The correct answer is that the oxidation process is completed in the Krebs cycle. This cycle involves the oxidation of acetyl-CoA, which leads to the production of NADH and FADH₂. These molecules carry electrons to the electron transport chain, where ATP is ultimately produced. The other options are misleading: while decarboxylation and reduction do occur, they are part of the cycle's processes rather than the end result. The cycle is not energy-consuming; rather, it prepares substrates for ATP generation.
