|
Definition
|
|
Term
| the law of "the conservation of energy" refers to the fact that? |
|
Definition
| energy cannot be created or destroyed but it can change forms |
|
|
Term
| according to the law of entropy: |
|
Definition
| in an exergonic reaction the products will have higher entropy than the reactants and in an endergonic reaction the reactants will have higher entropy than products |
|
|
Term

|
Definition
|
|
Term
| the high energy bond in an ATP molecule is located where? |
|
Definition
| between two phosphate groups |
|
|
Term
| ATP can be considered a type of ________ energy |
|
Definition
|
|
Term
| when glucose is converted into CO2 and H2O during respiration, which molecule in the reaction has the highest energy? |
|
Definition
|
|
Term
| what is an example of a coupled reaction? |
|
Definition
| hydrolysis reaction is used to fuel dehydration synthesis |
|
|
Term
| why, in an exergonic reaction, does the reactant contain more energy than the products? |
|
Definition
| the energy is contained in the complex bond of the reactant. when the bond is broken energy is released from the reaction so products do not have much energy |
