10 Questions
What is the main reason RBCs rely on anaerobic respiration?
Absence of mitochondria for aerobic respiration
What is the function of structural proteins in RBCs?
Maintain cell structure and enable shape change
What is the role of haemoglobin in RBCs?
Transport oxygen molecules
Why are RBCs biconcave in shape?
To provide greater surface area for gas exchange
What is the significance of the absence of a nucleus in mature RBCs?
Inability to repair
What are the structural features of a mature red blood cell (RBC)?
No nucleus, no mitochondria, no endoplasmic reticulum, presence of structural proteins, biconcave disks.
How does the absence of a nucleus impact the function of RBCs?
RBCs cannot repair themselves.
What is the role of haemoglobin in RBCs?
Haemoglobin binds to oxygen molecules for transport.
Why do RBCs rely on anaerobic respiration?
RBCs lack mitochondria for aerobic respiration.
What is the significance of the biconcave shape of RBCs?
It provides a greater surface area for gas exchange and enables them to fold up as they move through narrow blood vessels.
Test your knowledge of red blood cells (RBCs) with this quiz on their shape and structure. Explore the unique characteristics of mature RBCs, including their lack of nucleus and mitochondria, reliance on anaerobic respiration, and the role of structural proteins.
