Multiple Choice

A fully saturated hemoglobin molecule transports how many molecules of oxygen?

Previous problemNext problem

Verified step by step guidance

Understand the structure of hemoglobin: Hemoglobin is a protein found in red blood cells that is responsible for transporting oxygen. It consists of four subunits, each containing a heme group capable of binding one oxygen molecule.

Recognize the concept of saturation: A fully saturated hemoglobin molecule means that all four heme groups are bound to oxygen molecules.

Relate the number of oxygen molecules to the number of heme groups: Since each heme group binds one oxygen molecule, and there are four heme groups in a hemoglobin molecule, a fully saturated hemoglobin molecule will transport four oxygen molecules.

Review the options provided in the problem: The correct answer is the number of oxygen molecules transported by a fully saturated hemoglobin molecule, which is 4.

Conclude the reasoning: Based on the structure and function of hemoglobin, the answer is derived from the fact that each of the four heme groups binds one oxygen molecule, resulting in a total of four oxygen molecules transported.
