| Glycolysis | Splitting of glucose. |
| Gycolysis uses 2 ATP but creates | 4 ATP for a net gain of 2 ATP. |
| Anaerobic | No Oxygen required |
| Aerobic | Oxygen Required |
| Krebs Cycle | Pyruvic acid broken down into CO2. |
| Electron Transport Chain | Uses high energy electrons from NADH and FADH2 to convert ADP into ATP. |
| Alcoholic fermentation | Performed by yeast in absence of oxygen |
| Lactic Acid | Produced in muscle cells if not enough oxygen is present |
| Pyruvic Acid | 3-carbon end product of glycolysis |
| To regenerate NAD+ for glycolysis | The purpose of fermentation |
| Carbon dioxide | A waste product in alcoholic fermentation but NOT in lactic acid fermentation |
| Two types of high energy electron carriers | NADH and FADH2 |
| Number of ATP produced via aerobic cellular respiration | 36 |
| Location of electron transport chain in eukaryotes | the inner mitochondrial membrane |
| Electrons moving down electron transport chain | provides energy to move hydrogen ions into the intermembrane space |
| ATP synthase | joins a phosphate and and ADP to create ATP |
| Glycolysis | The first step of cellular respiration; takes place in cytoplasm |
| Two disadvantages to glycolysis in comparison to aerobic cellular respiration | 90% of the energy is still unused and it wll eventually run out of NAD+ |
| In the electron transport chain this acts as the final electron acceptor | Oxygen |
| Waste products of the electron transport chain | low energy electrons and hydrogen ions |
| A series of chemical reactions that begin with pyruvic acid from glycolysis | The Krebs Cycle |
| Alcoholic Fermentation produces this | alcohol, carbon dioxide, and NAD+ |
| Lactic Acid Fermentation produces this | lactic acid and NAD+ |
| The first step in cellular respiration is | glycolysis |
| Fermentation is... | anaerobic respiration |
| In glycolysis one glucose produces | two pyruvic acid |
| This process has a small gain in ATP, but is very fast | glycolysis |
