This is another input. Two ATPs are required to start up glycolysis. To the right of the large arrow, draw a semi-circle arrow that flows into and then out of the large arrow. Label the incoming (or input) arrow with the term “2 NAD+.” Label the outgoing (or output) arrow with the term “2 NADH.” Near the bottom of the page draw a line and label it: “The Bottom Line.”Under it, write “2 Net ATP.” This is the final output, and this completes our diagram of glycolysis. Your diagram shows you a quick summary of glycolysis: The inputs are glucose, 2 ATP, and 2 NAD+. The outputs are pyuvic acid, 4 ATP, and 2 NADH.The big result from glycolysis is the production of two molecules of ATP. This is useful cellular energy, but just a smidge. What about the other two products of glycolysis,pyruvic acid and NADH? Both of these products have potential energy that the cell can tap to produce much more ATP. However, unlike glycolysis, oxygen must be available to extract this remaining energy within the mitochondria. In the next MP3 Tutor session, we’ll complete this brochure as we cover the remaining steps of cellular respiration.I hope this has helped you understand glycolysis. Don’t forget to study all of your resources. There is a fair bit of material within your textbook and on your CD-ROM to help you with this topic. Good luck!
