Using the template below that represents the four levels of protein structure, place an X on each level that is expected to be altered as a result of the amino acid substitutions shown in Figure 1. Explain how the amino acid substitution shown in Figure 1 is most likely to affect the function of Receptor X.
Understand the Problem
The question is asking about the four levels of protein structure and how to identify which levels would be affected by specific amino acid substitutions. It also asks for an explanation of how a particular amino acid substitution might influence the function of a receptor.
Answer
Primary, secondary, and tertiary structures are altered.
The amino acid substitution will affect the primary, secondary, and tertiary structures of Receptor X. It can potentially alter the function if it affects a critical functional region.
Answer for screen readers
The amino acid substitution will affect the primary, secondary, and tertiary structures of Receptor X. It can potentially alter the function if it affects a critical functional region.
More Information
Amino acid substitutions can cause significant changes in protein folding and functionality by affecting hydrogen bonding, hydrophobic interactions, and disulfide bonds. These changes can disrupt the protein's active site or binding regions, leading to altered or lost functionality.
Tips
A common mistake is assuming only primary structure is affected. Secondary and tertiary structures often change as well due to folding dependencies.
