Question

structure is the result of two or more protein subunits assembling to form a larger, biologically active protein complex.target 1 of 4
2. Blank structure describes the alpha-helices and beta-sheets that are formed by hydrogen bonding between backbone atoms located near each other in the polypeptide chain.target 2 of 4
3. Blank structure is the sequence of amino acids in a protein.target 3 of 4
4. Blank structure is achieved when a protein folds into a compact, three-dimensional shape stabilized by interactions between side-chain R groups of amino acids.target 4 of 4

Answer 1

Here are the appropriate terms to fill in the blanks for each structure described:

1. **Quaternary structure** is the result of two or more protein subunits assembling to form a larger, biologically active protein complex.

2. **Secondary structure** describes the alpha-helices and beta-sheets that are formed by hydrogen bonding between backbone atoms located near each other in the polypeptide chain.

3. **Primary structure** is the sequence of amino acids in a protein.

4. **Tertiary structure** is achieved when a protein folds into a compact, three-dimensional shape stabilized by interactions between side-chain R groups of amino acids.
