Question

The energy released in a redox reaction is contained in the electrons released from the oxidized substrate. In a typical biological redox reaction, which product contains the energy released?

Answer 1

In a biological redox reaction ATP i.e adenosine tri phosphate is the product which contains the energy released.

Adenosine triphosphate (ATP) is the end product of cellular respiration, which is a catabolic pathway comprised of a series of steps that convert the chemical energy in glucose into the energy contained in ATP.

The available energy in glucose (and other sugars) resides within its electrons. These electrons (along with their energy) are removed and passed to intermediate electron carriers in a step-by-step process.

During cellular respiration, there is a relocation of electrons. This relocation results in the release of energy that is stored in food molecules, and the released energy is used to synthesize ATP.
