Cellular Respiration
Cellular respiration involes four metabolic pathways
| Term | Definition |
|---|---|
| Glycolysis: Where | takes places in the cytoplasm of a cell |
| Glycolysis: When | takes place when glucose is abailable |
| Glycolysis: Why | uses energiy stored in the chemical bonds of glucose to form atp-to provide energy |
| Glycolysis: How | glucose is oxidized to form pyruvic acid |
| Glycolysis: how | there is a net gain of 2 molecules of ATP |
| Glycolysis: How | @ molecules of NADH are generated to carry high-energy electrons- be used to make more ATP |
| Formation of Acetyl Coenzyme A: when | oxygen is available |
| Formation of Acetyl Coenzyme A: how | acetyl groups binds to coenzyme A, forming acetyle coenzyme A, which entenrs the Krebs Cylcle |
| Formation of Acetyl Coenzyme A: Where | transported into the mitochondria |
| Krebs Cycle: Where | takes place in the matrix (interior) of a mitochondrion |
| Krebs cycle: when | Takes place when oxygen is available |
| Krebs Cycle: why | releases more of the energy that was available in a molecule of glucose |
| Krebs Cycle: How | each of the 2 molecules of acetyl coenzyme A that enters the Krebs cycle gets oxidized to produce 2 molecules of CO2 |
| Krebs Cycle: how | 2 molecules of ATP are produce |
| Krebs Cycle: how | 6 molecules of NADH and 2 molecules of FADH2 are generated to carry high energy electrons |
| Electron Transport Chain: Where | takes place along the inner membrane of a mitochondrion |
| Electron Transport Chain: When | takes place when oxygen is available |
| Electron Transport Chain: Why | completes the release of energy that was stored in a glucose molecule |
| Electron Transport Chain: How | NADH and FADH2 transfer electrons and hydrogens ions to carriers to make ATP |
| Electron Transport Chain: How | oxygen takes low-energy electrons and combines with hydrogen ions to form water |
| How many ATp are made? | 36 ATP in a cell total |
| Krebs cycle ATP? | Doubles the amount of ATP a cell would use |
