Trivia: What is the iron-rich protein in red blood cells called?
Pantothenic acid
Cryo
Hemoglobin
Riboflavin
The correct answer is Hemoglobin
So why is this answer correct? : The hemoglobin in red blood cells contains iron, which allows the cells to pick up oxygen and distribute it throughout the body. The hemoglobin also gives red blood cells their color. After these cells deliver their oxygen, they pick up carbon dioxide and take it to the lungs, where it is exhaled and removed from the body.
