Where does glycolysis take place in the cell? In the cytosol What is the main product of glycolysis? Two three-carbon molecules of pyruvate How many ATP molecules are netted from one molecule of glucose during glycolysis? Two ATP molecules What type of phosphorylation occurs during glycolysis? Substrate-level phosphorylation What happens to each glucose molecule during glycolysis? It is broken down into two pyruvate molecules What are the steps involved in the energy-investing phase of glycolysis? 1. Glucose is primed using 2 ATP. 2. Glucose is converted to glucose-6-phosphate. 3. Glucose-6-phosphate is rearranged to fructose-6-phosphate. 4. Fructose-6-phosphate is phosphorylated to fructose-1,6-bisphosphate. 5. Fructose-1,6-bisphosphate is cleaved into DAP and G3P. 6. DAP is rearranged to form another G3P. What is the first step of glycolysis? ATP transfers a phosphate to glucose, forming glucose-6-phosphate What is the purpose of glucose priming in glycolysis? To convert glucose into a compound that can be cleaved into two three-carbon molecules What is formed from glucose-6-phosphate in step 2 of glycolysis? Fructose-6-phosphate How many ATP molecules are used in the priming phase of glycolysis? Two ATP molecules What happens during step 4 of glycolysis? The fructose-1,6-bisphosphate splits into DAP and G3P
