Thank you so much !! You are very lovely and this really helped me understand the ER along with other things in depth, whenever the teachers glossed over it in past classes. I love your videos and I have been watching them a lot recently! Thank you for keeping them up!
Answer for the question: Red blood cells (RBC) lack endoplasmic reticulum as the main function of RBCs is to exchange gases between lungs and the body. This requires the RBCs to be a little flexible to move through various parts of the body. If they have ER (which many mature RBCs do not have) the ER will use some of the gas carried by the RBC for synthesis of lipids and proteins. Hence, the lack of ER in RBCs is beneficial for gas exchange which is their main function. Thank you mam 🙏😊
Very well and Easily Explained! Loved it mam! Loved the visuals in this video! Excellent Editing! Hope we get many of these kind of Biology Videos!! :) Also, Congo for 1.1M Subscribers
If RBC's had ERs their surface area for absorption would be less, hence they are absent. If they were present they would decrease the functioning of the RBC.(PS I'm not sure If this is right 👀)
To Answer the questions asked at the end of the video:- Q. Why red blood cells do not have endoplasmic reticulum? Answer:- Red blood cells lack endoplasmic reticulum because they get rid of most organelles, including the endoplasmic reticulum, to make more room for carrying oxygen. Q. Would Endoplasmic Reticulum be useful for RBCs Answer:- Endoplasmic reticulum wouldn't help red blood cells because they're all about carrying oxygen and don't need the extra baggage of organelles like the endoplasmic reticulum, which is responsible for making proteins and lipids.
