Question

The complete oxidation of pyruvate by the step wise removal of :

• A. All the hydrogen atoms, leaving two molecules of $C{O}_2$
• B. All the hydrogen atoms, leaving three molecules of $C{O}_2$
• C. Two hydrogen atoms, leaving three molecules of $C{O}_2$
• D. None of the above

Answer 1

The correct option is C Two hydrogen atoms, leaving three molecules of $C{O}_2$

The complete oxidation of pyruvate by the step wise removal of all the hydrogen atoms, leaving three molecules of CO2.

Aerobic respiration

1. Pyruvic acid enters into the mitochondria.

2.Complete oxidation of pyruvate by the stepwise removal of all the hydrogen atoms,

leaving three molecules of CO2.

3The passing on the electrons removed as part of the hydrogen atoms to molecular

oxygen (O2) with simultaneous synthesis of ATP.

So, the correct option is, 'All the hydrogen atoms, leaving three molecules of CO2'.
