Function of Metabolism |
1. degrade macromolecule into smaller macromolecule and release energy - ATP 2. Release + conserve energy in the form of ATP or heat 3. smaller molecule to larger molecule needed for cell |
|
|
2 components of metabolism |
catabolism + anabolism |
|
|
What is catabolism |
harvesting energy during disassembly or breakdown of compounds breakdown of bonds of larger molecules to smaller molecules |
|
|
What is anabolism |
biosynthesis -- includes utilizing energy stored in ATP to synthesize and assemble subunits of macromolecules making up the cells |
|
|
What is enzyme? |
Protein catalyst that have great specificity for the reaction being catalyzed and the molecules acted on |
|
|
What is a catalyst |
substance that increase the rate of a chemical reaction without being permanently altered |
|
|
What is the mechanism of enzyme reaction |
speed up at the rate in which a reaction proceeds towards its final equilibrium |
|
|
energy of activation |
amount of energy which must be overcome for a reaction to proceed |
|
|
lowering activation energy.... |
enzymes accelerates |
|
|
what is the activation energy required to do |
bring the reacting molecules together in the correct way to reach transition state |
|
|
The active site of an enzyme consists of... |
a group of amino acids that are involved in making contacts with the substrates |
|
|
2 ways enzymes interact with a substrate |
lock and key model induced fit model |
|
|
Lock and key model |
rigid shaped precisely fit the substrate so that the correct substrate binds specifically and is positioned properly for reaction |
|
|
induced fit model |
an ezyme ma |
