Directions: Read the selection below on glycolysis. Rewrite this in your own words in two different ways.

"The word glycolysis means, 'splitting of sugar,' and that is exactly what happens during this pathway. Glucose, a six-carbon sugar, is split into two three-carbon sugars. These smaller sugars are then oxidized and their remaining atoms rearranged to form two molecules of pyruvate. (Pyruvate is the ionized form of pyruvic acid). ...the pathway of glycolysis consists of ten steps, which can be divided into two phases. During the energy investment phase, the cell actually spends ATP. This investment is repaid with dividends during the energy payoff phase, when ATP is produced by substrate-level phosphorylation and NAD+ is reduced to NADH by electrons released from the oxidation of the food (glucose in this example). The net energy yield from glycolysis, per glucose molecule is 2 ATP plus 2 NADH."

Taken from Biology (7th edition) by Campbell and Reece, Benjamin Cummings, 2005 (page 165).
