| What are the 4 levels of protein structure? | 1. Primary 2. Secondary 3. Tertiary 4. Quaternary |
| What does the primary structure of protein look like? | A linear sequence of amino acids |
| What does the secondary structure of protein? | chains of amino acids folded in 3 different ways |
| What does the tertiary structure of protein? | irregular folding that forms a complex 3D shape |
| What does the quaternary structure protein? | Two or more polypeptide chains |
| Many proteins control ....... | all metabolic processes within cells. |
| Which molecule is different in different amino acids? | The R group |
| What makes proteins different from each other? | Different numbers and proportions of amino acids. |
| Each protein has it's own... | particular sequence of amino acids. |
| ................ will ....... in different ways depending on their ........... | Polypeptides will fold in different ways depending on their function. |
