Which of the following statements about the catabolism of food is incorrect?
- A. Carbohydrates are oxidized in stage 1 to produce carbon dioxide and energy. This statement is incorrect because remember in stage 1, we have the digestion of carbohydrates to create our respective monosaccharides. So this is incorrect. So this is our answer.
- B. Acetyl CoA is the product of stage 2 Catabolism. That is true, we make Acetyl CoA which then goes into the citric acid cycle to produce energy as well as carbon dioxide.
- The electron transport chain in oxidative phosphorylation is the last stage of food catabolism. That is true. That eventually leads to the production of more ATP energy.
- The Citric acid cycle uses Acetyl CoA to produce energy. Yes. The Acetyl CoA that goes into the Citric Acid Cycle does produce energy as well as CO2. This statement is true.
So out of all our options, only option A is incorrect.
