|
An organism that's gets chemical energy from consuming other organisms |
Heterotroph |
|
|
|
Organism capable of converting sunlight into chemical energy (photosynthetic) |
Autotroph |
"Auto"matically produces energy with sunlight |
|
|
The breakdown of organic compounds is an ______ reaction. |
Exergonic |
Releases excess energy |
|
|
ATP synthesis by enzyme transfer of Phosphate group |
Substrate-level Phosphorylation |
I know what you're thinking. It's not "phosphate". It rhymes though. |
|
|
The oxidation of organic compounds to extract energy from chemical bonds. |
Cellular Respiration |
|
|
|
Aerobic Respiration |
Consumption of organic molecules and O2 to yield ATP |
|
|
|
ETC |
Electron transport chain |
|
|
|
_______ uses exergonic flow of hydrogen ions to phosphorylate ADP into ATP |
ATP Synthase |
"Synthesize" ATP |
|
|
Two major phases of Glycolysis: |
1. Energy investment a) Requires two ATP 2. Energy payoff a) regenerates four ATP |
|
|
|
Glycolysis occurs in the _____ of the cell. |
Cytoplasm |
Cell goo |
|
|
Pyruvate Oxidation |
1. In the presence of O2, pyruvate enters the mitochondrian 2. Pyruvate may be converted to acetyl CoA
|
|
|
|
Kreb's Cycle |
1. Takes place in mitochondria 2. Acetyl CoA joins the cycle by combining with oxaloacetate, forming citric acid. 3. Final four reactions decompose citric acid back into oxaloacetate |
|
|
|
ATP synthesis of a phosphate group powered by the redox reactions of the ETC |
Oxidative Phosphorylation |
|
|
|
A partial degradation of glucose that occurs in an absence of O2 |
Fermentation |
|
|
|
Proton motive force |
Hydrogen ion gradient |
|
|
|
Lactic Acid Fermentation |
Pyruvate is reduced by NADH to lactate |
|
|
|
Alcohol Fermentation |
Pyruvate is converted into acetaldehyde and then to ethanol |
|
|
|
Chemiosmosis |
Energy stored in a hydrogen ion gradient across a membrane is used to regenerates ATP |
|
|
|
Glycolysis |
Glucose »»» 2 Pyruvate |
