Haemoglobin transports oxygen in the blood of vertebrates. So, no, we would not survive without it!
The function of a red blood cell is to transport oxygen; it does this without having to carry out any metabolic functions, because the chemical hemoglobin has the capacity to absorb and to release oxygen by itself. Red blood cells do not undergo cell division, since they are made in the bone marrow. They are just packages of hemoglobin.
yes
The red blood cells don't loose hemoglobin. Hemoglobin is the protein the oxygen binds to. So I think a better question is " What is the colour of RBC's without oxygen?" And the answer in a dark red.
Yes, of course! Low Hemoglobin means anemia, and it is said that "there are not leukemia without anemia"
White blood cells and platelets are the blood cells without hemoglobin. It is found in red blood cells.
The importance of hemoglobin for erythrocyte function is that it gives them oxygen carrying abilities. Without hemoglobin, the erythrocyte would be unable to carry and transport oxygen where it needs to go.
It is a genetic adaptation; without nucleus more space for hemoglobin is free. And hemoglobin is the carrier of oxygen.
You need energy to survive, so you cannot survive without energy.
Giraffes cannot survive without water
The planet can survive without light, but you won't
Reduced hemoglobin gives blood its red color. When oxygen binds to hemoglobin, it becomes oxyhemoglobin, which is bright red. Without oxygen, hemoglobin reverts back to reduced hemoglobin, which is darker and gives blood a deeper red hue.
