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 glycolysis, glucose (a six carbon sugar) is split into two molecules of the three-carbon sugar pyruvate. This multi-step process yields two molecules of ATP (free energy containing molecule), two molecules of pyruvate, and two high energy electron carrying molecules of NADH. Glycolysis can occur with or without oxygen. In the presence of oxygen, glycolysis is the first stage of cellular respiration. In the abscence of oxygen, glycolysis allows cells to make small amounts of ATP through the process of fermentation. Glycolysis takes place in the cytosol of the cell's cytoplasm. However, the next stage of cellular respiration known as the citric acid cycle, occurs in the matrix of cell mitochondria. Below are the 10 steps of glycolysis: Step 1
