Term
|
Definition
| adding a phosphate group to ADP to create ATP |
|
|
Term
| Substrate Level Phosphorylation |
|
Definition
- occurs in glycolysis and Krebs cycle
- an enzyme transfers a P from a substrate to ADP
|
|
|
Term
| Oxidative Phosphorylation |
|
Definition
- Occurs in the Electron Transport Chain (ETC)
- Energy is released through a series of redox reactions along a gradient
|
|
|
Term
Three phases of Cellular Respiration |
|
Definition

- Krebs cycle/Citric Acid cycle
- Electron Transport Chain (ETC)
|
|
|
Term
|
Definition
- the sugar breaking step
- substrate level phosphorylation
- occurs in cytosol of the cell

|
Term
| Glycolysis - energy investment phase |
|
Definition
| 2 ATP used to break a 6-carbon sugar into 2 3-carbon sugars (G3P: glyceraldehyde-3-phosphate) |
|
|
Term
| Glycolysis - Energy payoff phase |
|
Definition
results in: - 4 ATP molecules, net of 2
- 2 molecules of NADH
- 2 pyruvate molecules
|
|
|
Term
| The Krebs Cycle (Citric Acid cycle) |
|
Definition
- cyclic series of redox reactions that occur in the mitochondria membrane
- oxidation of acetyl CoA
- reduction of electron carriers
|
|
|
Term
| conversion of pyruvate to acetyl CoA |
|
Definition
- junction between glycolysis and the citric acid cycle
- CO2 molecule diffuses out of cell and NADH is generated (1 per pyruvate)
