Question

For every 1 gram of hemoglobin, how much O₂ can be carried?

Answer 1

Hemoglobin, a protein found in red blood cells, can carry up to four oxygen molecules.

Step-by-step explanation:

Hemoglobin, a protein found in red blood cells, can carry up to four oxygen molecules. Each iron ion in hemoglobin binds to one oxygen molecule, allowing each hemoglobin molecule to transport four oxygen molecules. An individual erythrocyte, or red blood cell, can contain about 300 million hemoglobin molecules, enabling it to bind and transport up to 1.2 billion oxygen molecules.
