Long-Term Memory. A long-term memory is anything you remember that happened more than a few minutes ago. Long-term memories can last for just a few days, or for many years. Long-term memories aren't all of equal strength. Stronger memories enable you to recall an event, procedure, or fact on demandâfor example, that Paris is the capital of France. Weaker memories often come to mind only through prompting or reminding.
Glucose with 6 carbons is split into two molecules of 3 carbons each at Step 4. As a result, Steps 5 through 10 are carried out twice per glucose molecule. Two pyruvic acid molecules are the end product of glycolysis per mono-saccharide molecule.
In summary, a single glucose molecule in glycolysis produces a total of 2 molecules of pyruvic acid, 2 molecules of ATP, 2 molecules of NADH and 2 molecules of water. Although 2 ATP molecules are used in steps 1-3, 2 ATP molecules are generated in step 7 and 2 more in step 10. This gives a total of 4 ATP molecules produced. If you subtract the 2 ATP molecules used in steps 1-3 from the 4 generated at the end of step 10, you end up with a net total of 2 ATP molecules produced. For a detailed view of the 10 steps, see: Details of the 10 Steps of Glycolysis.
