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.

I found the exercise on the internet. Attached is an image with the words on the left and the sentences with the blank spaces on the right.

For the first sentence, the correct term is "oxidized" - when a compound reacts and electrons are lost to another species.
The word for the second sentence is "reduced" - when a compound reacts and electrons are gained from another species.
The word for the third sentence is "glucose" - glucose is the electron donor in glycolysis being oxidized.
The word for the fourth sentence is "pyruvate" - pyruvate is the resultant molecule from the oxidation of the glucose.
The word for the fifth sentence is "NAD+" - this is the compound that is reduced when glucose is oxidized.
The word for the sixth sentence is "NADH" - this is the reduced compound resultant from the glucose oxidation.
