In glycolysis, as in all the stages of cellular respiration, the transfer of electrons from electron donors to electron acceptors plays a critical role in the overall conversion of the energy in foods to energy in ATP. These reactions involving electron transfers are known as oxidation-reduction, or redox, reactions. Drag the words on the left to the appropriate blanks on the right to complete the sentences.

1. When a compound donates (loses) electrons, that compound becomes oxidized. Such a compound is often referred to as an electron donor.
2. When a compound accepts (gains) electrons, that compound becomes reduced. Such a compound is often referred to as an electron acceptor.
3. In glycolysis, the carbon-containing compound that functions as the electron donor is water.
4. Once the electron donor in glycolysis gives up its electrons, it is oxidized to a compound called oxygen.
5. NAD+ is the compound that functions as the electron acceptor in glycolysis.
6. The reduced form of the electron acceptor in glycolysis isNADH.
