What do blood cells use to capture and carry oxygen?

Answer 1

Shape: Circular shape = larger surface area which means more oxygen can get into the cell.

Structure: no nucleus = larger volume = more oxygen

No mitrochondia (the stuff in your cell that makes energy -oxygen + glucose) so it relies on anaerobic respiration (respiration without oxygen) as to not use up all the oxygen.

Example: If the red blood cell uses up the oxygen it is carrying, it would be like a Pizza delivery man eating up all the pizzas he's delivering. Now you don't want that so they ADAPTED so they wouldn't use up the oxygen

Answer 2

1.it has no nucleus , so there is more space for more hemoglobin to be packed

2.it contains haemoglobin, which is a molecule which binds reversibly with oxygen

3.its flexible and elastic-so that it can squeeze through the capillaries

Answer 3

In the middle of every heme group is one iron atom that is used to bind oxygen for bodily uses.

Answer 4

Red blood cells or hemoglobin
