Solution
Solution Steps
Step 1: Analyze the provided image and options
The image presents a simplified diagram of an antibody structure, numbered 1 through 6, along with a list of possible labels. We need to match the numbers on the diagram to the correct antibody components.
Step 2: Identify the components
Light chain, constant region: This is the lower portion of the "arm" of the antibody.
Light chain, variable region: This is the upper portion of the "arm" of the antibody.
Heavy chain, constant region: This is the lower "stem" section of the antibody, connected to both arms.
Heavy chain, variable region: This is the upper portion of the "stem" and the part of the arms closest to the stem section.
Disulfide bridge: These are not directly labeled but are represented by the short lines connecting the heavy and light chains.
Antigen-binding site/variable region: This comprises both heavy and light chain variable regions at the tips of the antibody "arms."
