In glycolysis, as in all the stages of cellular respiration, the transfer of electrons from electron donors to electron acceptor
s 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. Fill the words from brackets to the appropriate blanks to complete the sentences.
(NADH, NAD+, pyruvate, water, glucose, oxygen, reduced, oxidized)
1. When a compound donates (loses) electrons, that compound becomes __________. Such a compound is often referred to as an electron donor.
2. When a compound accepts (gains) electrons, that compound becomes ___________ . 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 _______
4. Once the electron donor in glycolysis gives up its electrons, it is oxidized to a compound called ________.
5. ____________ is the compound that functions as the electron acceptor in glycolysis. 6. The reduced form of the electron acceptor in glycolysis is.
People with the sickle cell mutation in both copies of the HBB gene produce proteins that clump together and lead to changes in the shape and behavior of red blood cells.
