|
ATP |
Powers the cell by using the energy from exergonic reactions to drive endergonic reactions |
|
|
|
Phosphorylation |
When ATP donates a phosphate group |
|
|
|
Enzyme |
Helps drive metabolic reactions, speeds up the process of chemical reactions, are involved in all cellular metabolism (reactions), lower the activation energy, and have a specific shape |
|
|
|
Substrate |
The reactant an enzyme works on is called it's... specific to each enzyme |
|
|
|
Active Site |
crevice where substrate binds to enzyme during a reaction |
|
|
|
Catalyst |
A substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change |
|
|
|
Activation Energy |
The energy required to start a reaction |
|
|
|
Induced Fit |
Binding of a substrate causes a change in shape, including an even closer fit with substrate |
|
|
|
Competitive Inhibitor |
Blocks the active site and substrate cannot bond to enzyme |
|
|
|
Allosteric Inhibitor |
Attaches to a site that is not the active site and changes the shape of the enzyme |
aka non-competitive inhibitor |
|
|
Feedback Inhibitor |
Pathway has a product which blocks the action of enzymes early in the pathway |
negative and turns itself off |
