|
Term
|
Definition
| energy of motion (mechanical) |
|
|
Term
| 1st law of thermodynamics |
|
Definition
| Conservation of energy- energy cannot be created or destroyed, but it can be changed from one form to another |
|
|
Term
| 2nd law of thermodynamics |
|
Definition
| entropy- every energy transformation increases disorganization- energy is lost as heat as energy is converted from one form to another |
|
|
Term
|
Definition
| a process with a net release of free energy |
|
|
Term
|
Definition
| a process which requires an input of energy |
|
|
Term
|
Definition
| the use of exergonic process to drive an endergonic process |
|
|
Term
|
Definition
mechanical- beating of cilia, muscle contractions
transport- pumping of molecules and ions across a membrane
chemical- pushing endergonic reactions |
|
|
Term
|
Definition
| a nucleotide with adenine for the base and 2 additional phosphate groups attached |
|
|
Term
|
Definition
| a molecule that increases the speed of the reaction without being consumed in the reaction |
|
|
Term
|
Definition
| reactants in an enzyme- catalyzed reaction |
|
|
Term
|
Definition
| location where substrates attach |
|
|
Term
|
Definition
| non-covalent complex composed of a substrate bound to the active site of the enzyme. |
|
|
Term
|
Definition
| the molecules formed from the reaction |
|
|
Term
|
Definition
| all reactions require a certain amount of energy necessary to bring the molecules close enough with enough energy, enzymes lower the amount of energy needed |
|
|
Term
|
Definition
99% are proteins
speed up reactions
highly selective
function optimally at certain temps and pH levels
regulated |
|
|
Term
| 2 ways enzymes are regulated |
|
Definition
Inactive enzyme- substrate doesn't fit into active site
Enzyme inhibition- a molecule binds to active site to prevent a substrate from binding |
|
|
Term
|
Definition
chemical reactions in cells occur in a series of linked reactions
A>B>C>D>E>F>G |
