Q: Proteins can assume four structures. What are they? | A: Primary, Secondary, Tertiary, and Quaternary. |
Q: What determines the primary structure of protein? | A: The sequence of amino acids. |
Q: What are the secondary structures of protein? | A: Alpha helix and beta pleated sheets. |
Q: True or false? A secondary protein structure is the result of weak bonds formed between amino acids. | A: True! |
Q: Tertiary structures are 3 dimensional structures. Name the two major shapes. | A: Globular and Fibrous. |
Q: True or false? A quaternary structure is two or more proteins joined together to form a multimeric protein. | A: True! |
Q: What is a dimer? | A: Two proteins bond together. |
Q: What is a trimer? | A: Three proteins bond together. |
Q: Proteins must have a specific shape to have proper function. What is it called when a protein loses its shape? | A: Denaturation... which can be either reversible or irreversible. |
