| Where does the process of glycolysis take place? | Cytosol |
| What are the two main reactants of cellular respiration? | .,  |
| What are the two main products of cellular respiration? | .,  |
| True or false: Oxygen is required during glycolysis. | False: None of the reactions of glycolysis require an oxygen molecule as a reactant. |
| What is the total possible net gain of ATP from one molecule of glucose that goes through aerobic cellular respiration? | 38 ATP |
| How many ATP have to be used to get glycolysis started? | 2 ATP need to be broken down to get glycolyis started. Later in glycolysis, 4 ATP are generated to produce a net gain of 2 ATP. |
| How many ATP can be generated from one molecule of glucose during glycolysis? | 2 ATP per molecule of glucose can be generated during glycolysis. Although 4 ATP are actually produced, 2 were needed to get the reactions going, so you have to subtract these from the 4 for a net gain of 2.. |
| Glucose is broken down into 2 molecules of ____________ by the end of glycolysis. | pyruvic acid (a.k.a. pyruvate) |
| _____ molecules of pyruvic acid (pyruvate) can be generated from 1 molecule of ______ during glycolysis. | 2 (molecules of pyruvate), (from 1 molecule of) glucose |
| Besides pyruvic acid, which 2 high energy molecules are generated during glycolysis? | 2 ATP and 2 NADH are generated during the process of glycolysis using the energy that was originally in one molecule of glucose. |
Which stage of cellular respiration is being depicted by this picture?,  | Glycolysis |
| Which stage requires ATP to be broken down into ADP? | Glycolysis |
| During glycolysis, one of the steps converts glyceraldehyde-3-phosphate to 1,3-biphosphoglyceric acid. In the process, an NAD+ molecule strips 2 high energy electrons and a hydrogen atom from the glyceraldehyde-3-phosphate. Which molecule was oxidized and which was reduced? | The NAD+ was reduced when it accepted negatively charged electrons (and a hydrogen) to become NADH. Because the glyceraldehyde-3-phosphate lost electrons, it is said to have been oxidized. Remember, LEO says GER. |
| Where will the NADH produced during glycolysis take the high energy electrons that it is temporarily storing? | The NADH will take the electrons, and dump them off, in the electron transport chain. |
| The original organic molecule that entered glycolysis is a ___-carbon molecule while the final organic molecule product of glycolysis is a ____-carbon molecule. | 6-carbon (glucose) --> 3-carbon (pyruvate) |
