Glycolysis By Seth & Ethan

Introduction �Glycolysis occurs in most organisms, animal and plant �It’s products are necessary in order for cellular respiration to occur �It is not a part of cellular respiration �It’s products are used in cellular respiration �It takes place in the cytosol �Does not require oxygen

Initial Steps �Glycolysis first uses an ATP to energize a glucose into glucose-6 -phosphate �The second ATP is used to split this into two three carbon chains each with one phosphate �The two ATP, now with less energy, have become two ADP

Following Steps �Both chains of carbon gain a phosphorous, and transfer two electrons and a hydrogen ion �It transfers these electrons and hydrogen ion to NAD+, each chain to a separate NAD+ �The addition of these electrons and hydrogen ion changes it into NADH �These resulting molecules together contain two high energy phosphates

Final Steps �The high energy phosphates convert the ADP from earlier into ATP �This symbolizes a net gain of two ATP in glycolysis �In this process those three carbon chains undergo reactions to form 2 pyruvate molecules

In Summary �Two ATP turns six carbon glucose into two three carbon chains �Those chains transfer electrons and ions to two NAD+ to form two NADH �The three carbon chains undergo reactions to form pyruvate �It results in a net gain of two ATP after the formation of the NADH
