|
|
Term
|
Definition
| a pair of reactions, one exergonic and one endergonic, that are linked together such that the energy produced by the exergonic reaction proived the energy needed to drive teh endergonic reaction. |
|
|
Term
|
Definition

|
Term
|
Definition
| pertaining to a chemical reaction that requires an input of energy to proceed. |
|
|
Term
|
Definition
| a molecule that stores energy in high energy chemical bonds and realeases the energy to drive coupled endothermic reactions. In cells ATP is teh most common enegery carrier molecule. |
