Hemoglobin is not a living thing. Hemoglobin is simply a molecule capable of temporarily binding with oxygen and carrying that oxygen to where it is needed, then giving it up and returning to be reoxygenated. Hemoglobin is present in red blood cells, but does not metabolize, neither does it generate nor utilize energy itself, generally considered parameters that define 'living'.
Red blood cells lose their nucleus during maturation in order to make room for more hemoglobin, the protein responsible for transporting oxygen in the blood. This allows the cell to have a biconcave shape for efficient gas exchange and a larger surface area-to-volume ratio. The lack of nucleus also enables the red blood cell to live longer in the bloodstream.
An analogy of a nucleus is that it is like a brain. It controls the rest of the body and what goes on mostly. Without it, you body would get confused and then you would die. (the cell would die.) This nucleus houses the DNA, like your brain carries special information on how to do things. Just like DNA does. Also, without DNA, you wouldn't be able to live either.
Llama hemoglobin has a higher affinity for oxygen because it has a unique structure that allows it to bind more tightly to oxygen molecules, enabling llamas to efficiently extract oxygen from the thin air at high altitudes where they live.
You can live without your spleen, as it is not essential for survival.
The red blood cell is really just a package of hemoglobin, which does not require any kind of metabolic process to perform its function. The absorption and release of oxygen by hemoglobin is spontaneous, it does not have to be driven by any other chemical process. This is quite unlike other cells which have functions that require some kind of biochemical activity that would be directed by the genetics of the cell nucleus and assisted by organelles such as mitochondria etc. Muscle cells need these things to be able to contract or relax. Nerve cells need these things to be able to transmit or receive nerve signals. But red blood cells perform their function automatically, due to the chemical properties of hemoglobin.
No
Haemoglobin transports oxygen in the blood of vertebrates. So, no, we would not survive without it!
Yes, that is about average. Red blood cells, when forming, eject their nucleus to make more room for hemoglobin. Without a nucleus, the cell has no ability to make repairs to itself and after about 120 days, it is worn out enough that it gets recycled in the liver and spleen.
Bacteria lacking a nucleus
I dont know, ask a proffesional
No. Hemoglobin is required to transport O2, a constant requirement for human life.
in the blood
they still have DNA in them so the DNA controls the cell
It's impossible to be able to obtain free demos from the Xbox Live marketplace without having a working connection for one, and without having a working gold membership account.
no
Possibly because the gene of a plant or animal is in the nucleus and the country would display how the people that live there are by having a, metaphorically speaking, genetic structure for how people live and act in this region but also that the nucleus is the brains of a cell, makes the decisions etc. this is wat the government does for a country
RBC's are made up almost entirely of Hemoglobin, a substance that binds with oxygen and releases carbon dioxide. The chemical reactions within the cell are carried out naturally and regularly, and consequently, do not need to be monitored or regulated by a nucleus, and as long as there is oxygen for the hemoglobin to bind to, carry, and distribute, the RBC will live about four months.
