| Question | Answer |
|---|---|
| what are proteins made from | amino acids |
| How many different amino acids are used in proteins | twenty (20) |
| What 4 elements do all proteins contain | Carbon, Hydrogen, Oxygen & Nitrogen |
| What element do only SOME proteins contain | sulfur |
| What bonds hold proteins together | Peptide bonds |
| what determines the structure of a protein | The order of amino acids determines the structure of a protein |
| What determines how a protein will work | The structure of a protein will determine how it works |
| TRUE OR FALSE: "Each protein has its own special shape" | True! |
| What is a proteins "primary structure" | The order in which the amino acids are arranged in a protein chain is called the "primary structure" |
| What is the secondary structure of a protein | Some chains coil up or fold, the coils and pleats are the secondary structure |
| What are the coils and pleats in a protein held together by | weak forces of chemical attraction or "Hydrogen Bonds" |
| Explain a proteins "tertiary structure" | The tertiary structure occurs when the chain of amino acids are folded into a ball like shape that's held together by a mixture of weak chemical bonds (hydrogen bonds) and stronger bonds (e.g Disulfate bonds) |
| Give an example of a "stronger bond" | Difulfate bonds |
| What structure is this | Tertiary structure |
| What structure is this | Primary |
| What structure is this | secondary |
