Term
| What are proteins made of? |
|
Definition
| Amino-acid units linked into chains. |
|
|
Term
| What are the structural components of an amino acid? |
|
Definition
| Tetrahedral carbon, carboxyl group, amino group, singular hydrogen, side chain. |
|
|
Term
| Primary Structure of Proteins |
|
Definition
| The order of the amino acids. |
|
|
Term
| Secondary Structure of Proteins |
|
Definition
| Hydrogen bonds form between peptide chains; alpha helices or beta-pleated sheets. |
|
|
Term
| Tertiary Structure of Proteins |
|
Definition
|
|
Term
| Quaternary Structure of Proteins |
|
Definition
| Link protein units together that are not bound by peptide bonds. |
|
|
Term
| What is the first step for the enzyme model? |
|
Definition
| Initiation: Reactants bind to the active site in a specific orientation, forming an enzyme-substrate complex. |
|
|
Term
| What is the second step for the enzyme model? |
|
Definition
| Transition state facilitation: Interactions between enzyme and substrate lower the activation energy required. |
|
|
Term
| What is the third step for the enzyme model? |
|
Definition
| Termination: Products have lower affinity for active site and are released. Enzyme is unchanged after the reaction. |
|
|
Term
|
Definition
| A regulatory molecule directly binds the active site by binding to the enzyme's active site, so the substrate cannot bind. |
|
|
Term
|
Definition
| A regulatory molecule binds to somewhere other than the active site. |
