Definition
| what type of reaction occurs during cellular respiration? |
|
|
Term
|
Definition
| exergonic (releases energy); breaking down large molecules into smaller molecules |
|
|
Term
|
Definition
| endergonic (requires input of energy); larger molecules are built from smaller molecules |
|
|
Term

|
Definition
| four main stages of cellular respiration? |
|
|
Term
| electron (hydrogen) carriers |
|
Definition
| both NAD & FAD (coenzymes) remove 2 hydrogen atoms and their electrons from a molecule and carry them to the electron transport chain |
|
|
Term
|
Definition
| non-protein substance associated with an enzyme |
|
|
Term
| substrate-level phosphorylation |
|
Definition
| generates ATP by transferring a phosphate group from a molecule directly to an ADP |
|
|
Term
| oxidative phosphorylation |
|
Definition
| generates ATP by removing electrons from a carrier and passing them through the electron transport chain. releases the most energy |
