| Question | Answer |
| How many "steps" are in glycolysis? | 10 enzyme-catalyzed "steps" (reactions). |
| What is the first phase of glycolysis called & how many "steps" are there? | The energy investment phase, consisting of 5 "steps". |
| What is the last phase of glycolysis called & how many "steps" are there? | The energy payoff phase, also consisting of 5 "steps". |
| What happens during glycolysis, in general terms? | Enzymes break down 1 molecule of glucose into 2 molecules of pyruvate (3-carbon compound); energy is released in the process, producing ATP & NADH. |
| Where does glycolysis occur in the mitochondria? | The cytosol of the mitochondria. |
| List the process of glycolysis (hit all 10 "steps" & the products). | |
| What is the net gain of ATP after the whole process? | 4 ATP made - 2 ATP invested = 2 ATP net gain. |
| How many high electron energy carriers are made during glycolysis? | 2 NADH are made. |
| What is the overall equation of glycolysis? | Glucose + 2 ADP + 2 P + 2 NAD+ --> 2 Pyruvate + 2 NADH + 2 ATP |
| What kinds of reactions occur during glycolysis? | Phosphorylation, isomerization, oxidation, redox, lysis, dehydration. |
| Define phosphorylation. | The transferring of a phosphate to another molecule. |
