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.
During prophase I, the homologous chromosomes condense and become visible as the x shape we know, pair up to form a tetrad, and exchange genetic material by crossing over.
The somatic cells of fruit flies contain eight chromosomes, which means they have two sets of four chromosomes. Meiosis is the process by which sex cells are produced. Sex cells are haploid, which means they have one set of chromosomes.
