Chapter 37, Problem 3STP

Summary Introduction

Introduction:

An antibody is also known as immunoglobulin. It is a large, Y-shaped protein produced mainly by plasma cells that are used by the immune system to neutralize pathogens such as pathogenic bacteria and viruses.

Answer to Problem 3STP

Correct answer:

The correct answer is option (A) They allow for an enormous number of possible antibodies to form.

Explanation of Solution

Explanation/justification for the correct answer:

Option (A) They allow for an enormous number of possible antibodies to form. They allow for an enormous number of possible antibodies to form. Antibodies are immunoglobulin’s that contains four polypeptides that are two heavy chains and two light chains. (2) and (3) are the variable regions that include the ends of the heavy and light chains. So, the correct answer is option (A).

Explanation for incorrect answer:

Option (B) They are created by the T cells in the immune system. Antibodies are immunoglobulin’s that contains four polypeptides that are two heavy chains and two light chains. (2) And (3) are the variable regions that include the ends of the heavy and the light chains. That is option (B) is not correct.

Option (C) They help reduce the number of antibodies that form. No, they do not help to reduce the number of antibodies they form. Hence, it is not correct.

Option (D) They help to stimulate the inflammatory response. They allow for an enormous number of possible antibodies to form. So, it is not correct.
