Protein Structure and Function Worksheet

Protein Structure and Function

Read each question carefully and answer to the best of your ability. This worksheet covers the structure and function of proteins.

1. Proteins are polymers made up of repeating monomer units called  .

2. The specific sequence of amino acids in a polypeptide chain is known as the   structure of a protein.

3. Alpha-helices and beta-pleated sheets are examples of   protein structures.

4. The overall three-dimensional shape of a single polypeptide chain is its   structure.

5. When a protein loses its native shape due to changes in pH or temperature, it is said to be  .

1. Which of the following bonds is responsible for linking amino acids together to form a polypeptide chain?

2. The function of a protein is primarily determined by its:

1. Briefly describe the four levels of protein structure (primary, secondary, tertiary, and quaternary).

2. Explain the importance of protein folding for its biological function.

1. All proteins have a quaternary structure.

2. Enzymes are a type of protein that speed up biochemical reactions.

Observe the diagram of protein structure below and answer the following question:

1. The image above shows a ribosome, which is composed of ribosomal RNA and proteins. Based on your understanding of protein synthesis, explain the role of proteins within the ribosome's function.
