Question

Mark the incorrect statement.

• A. Breaking of C–C bonds of complex organic molecules by oxidation in cells leading to the release of a lot of energy is called cellular respiration
• B. Initial stage of cellular respiration takes place in cytoplasm
• C. Incomplete oxidation of pyruvate by the stepwise removal of all the hydrogen atoms leaves three molecules of $C{O}_2$
• D. TCA cycle starts with the condensation of acetyl group with OAA and $H_{2}O$ to yield citric acid

Answer 1

The correct option is C

Incomplete oxidation of pyruvate by the stepwise removal of all the hydrogen atoms leaves three molecules of $C{O}_2$

In aerobic respiration, the complete oxidation of pyruvate by stepwise removal of all hydrogen atoms leaves three molecules of $C{O}_2$​. Hence, option c is the incorrect statement.
