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 oxidation?
a) the shared electrons in c-o bonds spend less time close to the carbon nucleus than the 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.
