Why does glucose contain more energy than carbon dioxide?

Answer 1

Glucose is a larger molecule that has many high energy bonds which store energy. ATP is a simple small molecule that contains only 1 high energy bonds.

This is why one glucose molecule will create several ATP molecules.

Answer 2

ATP is "more usable" because it is the form in which the cell can fuel its metabolic processes. Glucose is essentially a raw material. It undergoes one or more metabolic pathways (Glycolysis, Oxidative Phosphorylation, etc.) in order to yield ATP molecules that are immediately usable as energy.

Think of of glucose as an ingredient in a process that yields the final, readily usable product: ATP.

Answer 3

Glucose is a complex molecule that contains chemical bonds with high potential energy that can be released through metabolic processes. Carbon dioxide, on the other hand, is a simple molecule with lower energy content because it has already undergone oxidation reactions that released much of its stored energy.

Answer 4

The glucose molecule converts the energy into two molecules of ATP.

Answer 5

Because the formula for glucose is c6h12o6 therefore it has more energy then co2 because it is more saturated with hydrogens.
