each hemoglobin molecule can carry how many oxygen molecules?

Step 1: Define the Problem

Identify how many oxygen molecules a single hemoglobin molecule can carry.

Step 2: Break Down the Problem

Understand the structure and function of hemoglobin in relation to oxygen binding.

Step 3: Apply Relevant Concepts

Hemoglobin is a protein found in red blood cells that is responsible for transporting oxygen. Each hemoglobin molecule consists of four subunits, each containing an iron atom that can bind to one oxygen molecule.

Step 4: Analysis, Verify and Summarize

Since each of the four subunits can bind one oxygen molecule, a single hemoglobin molecule can carry a total of four oxygen molecules.

Final Answer

A hemoglobin molecule can carry four oxygen molecules.
