Answer:
Glycolysis is a series of reactions that take place in the cell cytoplasm. It involves the oxidation of glucose into pyruvate (a 3 carbon compound), that produces (overall)ATP and reduced NAD: an enzyme that carries hydrogen. The number of carbons in each of these compounds is indicated in the green circle.
The carriers FAD and NAD bring the hydrogen and it separates to H+ and electrons (e-). The electrons pass from carrier to carrier and loose energy. This is used to synthesize ATP.
However, there are a lot of hydrogen ions, that unless they are removed, they'll cause a large increase in pH. Therefore, oxygen reacts with the ions to remove it and produce water. This is what the oxygen you inhale is used for (in terms of respiration).

Answer:
Crossing over
Explanation:
Crossing over is the process during which two chromatids of two homologous chromosomes exchange part of their genetic segments. It occurs during the pachytene stage of prophase I of meiosis I.
Linked genes are mostly inherited together and do not exhibit independent assortment. However, when linked genes are present far apart from each other on the same chromosome, crossing over can occur between them to produce recombinant chromatids. Therefore, crossing over can break the linkage and produce recombinant progeny as it occurs during the independent assortment of unlinked genes.
