alleryRespiration is the breaking of which bonds through oxidation in cells?
ACarbon to carbon
BCarbon to chlorine
CCalcium to carbon
DCalcium to chlorine
Answer & Solution
Correct answer: A. Carbon to carbon
1. Food molecules are built on a carbon skeleton.
2. Breaking that skeleton releases the energy.
3. Respiration is the breaking of the carbon to carbon bonds of complex compounds through oxidation.
4. So the answer is carbon to carbon.
