When carbohydrates are oxidized, the C-H bonds of the carbohydrate become C-O bonds of carbon dioxide. Oxidation is defined as a loss of electrons, but carbon does not become positively charged in the process. Why then is this considered carbon oxidation?
A. The shared electrons in C-O bonds spend
less time close to the carbon nucleus than
shared electrons in C-H bonds.
B. Electrons in the C-O bonds are higher
energy than the electrons in the C-H bonds.
C. C-O bonds in CO2 are double bonds, and
C-H bonds are single bonds.
D. The phosphate groups of ATP are ionized,
and carbons donate those electrons.
