This MICROBIOLOGY stack covers the section of chapter 2 entitled PROTEIN STRUCTURE. (blank)
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.
