Matching

Indicate which of the following statements are true (T)or and which are false (F)with reference to immunoglobulin structure.

Premises:

Responses:

A flexible hinge region holds the heavy chain and light chain together.

False

λ and κ light chains have different functions.

True

The heavy-chain constant region is responsible for the effector function of immunoglobulins.

The antibody secreted by a plasma cell has a different specificity for antigen than the immunoglobulin expressed by its B-cell precursor.

The amino-terminal regions of heavy and light chains of different immunoglobulins all differ in amino acid sequence.
