Hemoglobina

The video explains the role of hemoglobin in transporting oxygen in the blood. It highlights that 97% of the dry weight of mammalian red blood cells is hemoglobin. When oxygen binds to hemoglobin, it forms oxyhemoglobin, which gives arterial blood its bright red color.

• Plasma

• Hemoglobin

What happens when oxygen binds to the hemoglobin molecule?
