Definition
| Cannot be created or destroyed, but can be changed. All cells require energy. |
|
|
Term
| Every aspect of life centers on what? |
|
Definition
| Converting energy from one form to another. |
|
|
Term
| What are the two types of energy? |
|
Definition
|
|
Term
| What is Potential energy? |
|
Definition
| STORED ENERGY. (Chemical bonds- the stronger the bond, the more potential energy, battery, ball on top of a hill) |
|
|
Term
|
Definition
| ENERGY OF MOVEMENT. (Motion to matter, LIGHT, heat, electricity) |
|
|
Term
| What is the first law of thermodynamics? |
|
Definition
| Law of conservation of energy. Total amount of energy is constant, energy cannot be created or destroyed. Restrictions on the direction of energy transfers. (EX: Amount of energy an organism uses cannot exceed the amount of energy it takes in.) |
|
|
Term
| What is the second law of thermodynamics? |
|
Definition
| When you exchange energy you always LOSE some. Unless energy is added to the system, processes that proceed spontaneously result in an INCREASE of randomness or disorder. |
|
|
Term
|
Definition
| tending toward randomness or disorder (2nd law of thermodynamics) |
|
|
Term
|
Definition
| A form of potential energy which is stored in bonds. |
|
|
Term
| What is the formula for cellular respiration? |
|
Definition
|
|
Term
| What happens during cellular respiration? |
|
Definition
| Chemical bonds are broken releasing ATP |
|
|
Term
| Is ATP a storage molecule or an immediate energy source? |
|
Definition
| Immediate energy source. It's like a stick of dynamite- you make it and it explodes. |

|
|
Term
|
Definition
| Where only one molecule will fit. Makes enzymes very specific. |
|
|
Term
|
Definition
| When substrates bind to active site and and shape changes. |
