What is the primary benefit of the biconcave disc shape of a red blood cell?

• Increased flexibility

• Ability to engulf pathogens

• Increased surface area for gas exchange

• Production of hemoglobin

What is the main reason why red blood cells lack mitochondria?

• To increase their flexibility

• To allow for cell division

• To maximize the space available for hemoglobin

• So the cell won't use up the oxygen that it is carrying

The protein found in red blood cells responsible for carrying oxygen is:

• Myoglobin

• Hemoglobin

• Actin

• Myosin
